5

AFTER MY PARENTS FINISHED CHEWING ME OUT FOR NOT telling them about Paul’s trip to the Triadverse to find a cure for Theo, they settled in with me for the wait.

“Paul said he’d come back after twenty-four hours,” I told them as we sat up late on the back deck. “Or as close to it as he can manage. Even if he hasn’t found a cure for Theo yet, he’ll check back in just to let us know he’s safe.”

“Twenty-four hours!” My father shook his head, expression grim. “If Conley’s figured out how to monitor dimensional traffic, his people could be on Paul within minutes.”

“But that dimension’s Paul already got away from Triad,” I protested. “He escaped to Ecuador.”

This placated my dad not at all. “You think a global tech mogul like Wyatt Conley can’t hire operatives in Ecuador?”

Mom laid her hand on Dad’s shoulder. “Henry, please. This isn’t helping.”

I imagined Paul being held prisoner. Being interrogated by men to whom the Geneva Convention wouldn’t apply. My stomach cramped, as if in sympathetic pain. Had we been stupid to leave my parents out of it? I said, “Could you have done something to help him get into the Triadverse without being detected?”

“Nothing Paul isn’t capable of doing himself,” my mother replied. “He has a chance. Paul knew the odds. He did this to help his best friend. We should respect his decision.”

She was speaking to my father then, who didn’t reply. I figured it would be a long time before we were forgiven—or, at least, that it wouldn’t happen until Paul had given Theo a miracle cure that restored him to health.

But it didn’t take that long.

By the time thirty-six hours had passed and Paul still hadn’t returned, Dad was beyond yelling at me about it. Like the rest of us, he was too frightened for that.

“They wouldn’t kill him,” I said, pacing through the great room. “Would they?”

“Unlikely. Conley would be a fool to simply eliminate Paul rather than taking him captive as leverage.” My mother turned out to have an instinct for criminal behavior. “Yet Conley would also be foolish not to tell us he’s taken Paul captive. My instinct is therefore to assume that Paul remains at liberty. But if he is free, why hasn’t he returned?”

“Maybe he’s in the heart of working on Theo’s cure,” Dad said.

“Maybe,” I repeated. But none of us believed it.

Two full days after Paul’s journey into the Triadverse, none of us had slept more than a couple of hours at a time. Dad now believed Conley had captured Paul but was making us sweat it out; Mom theorized that Paul could have experienced a Firebird malfunction.

In either case, we knew there was only one way to find out for sure.

“I should be the one to go,” my father said. “I’ve left these travels to the young ones for long enough.”

“Dad, no. I’m the perfect traveler. It should be me.”

For the past three and a half months, Paul and I had periodically visited brand-new universes, to further test the Firebirds and to see more of the multiverse’s wonders. Mostly I saw a lot of dimensions very similar to my own, but where my parents were working on different research, teaching at a different university, et cetera. But even those worlds could offer a wealth of data the Firebird project team could use. I went because I could travel more effectively than anyone else; Paul went with me because he had the experience, and because it was dangerous to travel alone.

Now, however, I would have to make a trip on my own—the riskiest one of all.

Mom sat at the rainbow table, her hands steepled in front of her. “You go in. You immediately use the locator function to find Paul. As soon as you know where he is, you return and give us the full report. We’ll decide how to proceed from there.”

“Okay.” Did that mean actually reach Paul if I could, or just get the information? I decided I’d make that decision when I arrived in the Triadverse.

“If Paul’s Firebird malfunctioned,” Mom continued, “he may have tried to return to our universe but instead traveled to a new dimension. Your Firebird is set to track his. You’ll be able to follow in his dimensional footsteps, so to speak—to travel to whatever world he might have ended up in.”

“Please.” Dad’s voice broke. “Let me be the one to do this. For all three of you to be in danger at once—”

My parents love Paul and Theo only slightly less than they love Josie and me. They’re the sons Mom and Dad never had. I knew they were as afraid for Paul as I was, but seeing my father this upset ripped me open inside. “Dad, I can do this better than anyone else. I have the ability; I have the experience. Meanwhile, you have the actual scientific knowledge about the Firebirds. If you go, and Conley winds up capturing you, too? We’re going to be totally screwed.”

This made him laugh a little, as it was meant to. I knew I couldn’t make this situation easier for any of us, but at least I could get my father to accept what had to be done.

Or maybe not. Maybe Dad still hated the idea of my going to rescue Paul as much as he ever had. But he didn’t object again, not even in the moment when I embraced them both and leaped out of my own world—

—and thudded into my Triadverse self, who was at a coffee shop, staring at her phone. I gripped the side of the table and looked around, half expecting Triad goons to barge through the door with tasers. Instead, I only saw the usual crowd of people tapping on laptops or talking over their cappuccinos.

Immediately I used the Firebird locator function—and it came up zero. My Paul was nowhere in this dimension.

At that moment, it seemed like good news. Conley hadn’t captured Paul! It was just a Firebird malfunction, like Mom said. With a smile on my face, I set the tracker into motion, so the Firebird would travel along Paul’s path and take me to him.

Which is how I wound up in medieval Rome, questioning everyone I could find about “Paolo Markov of Russia” while trying to dodge accusations of witchcraft.

How I ended up here, and now, bargaining with Wyatt Conley for Theo’s cure and Paul’s soul.

Cardinal Conley gets to his feet and straightens himself. It hits me for the first time how ridiculous Wyatt Conley looks in clerical robes. It seems as if no universe could ever allow him to be a man of the cloth; whatever else Conley is, he’s not a religious, moral person. Then again, in the Middle Ages, most cardinals weren’t. The position let men gain tremendous influence and political power. No wonder this universe’s Conley became a cardinal.

As solemnly as the church elder he pretends to be, Conley says, “If you’re worrying about being splintered yourself, Marguerite, let me put your mind at ease. Perfect travelers can’t splinter—it’s yet another of our advantages. But generally, a soul can be broken into as many pieces as you’d like. Dozens, even hundreds.”

The horror dizzies me. Is Paul torn apart even now, scattered across the entire multiverse?

“Don’t worry,” Conley says, in a tone that could be mistaken for concern if you didn’t know him well. His red robes look almost satanic in the firelight. “I went easy on you, didn’t smash him up too much. Four pieces, in four different dimensions. You just rescued the first one! See how easy it is? I gave you this splinter as a sign of good faith.”

Does he want me to thank him? “What do I have to do to get the coordinates for the other three dimensions?” Three more pieces of Paul’s soul. Three more worlds I have to find, and three more rescue missions.

Disgustingly satisfied with himself, Conley says, “I have a few errands for you.”

There it is—Triad Corporation’s iron fist closing around me.

But if this is the price of Paul’s soul, I have to pay.

“Let me explain precisely what I need.” Conley stands up straighter; his cardinal’s robes lend him an authority he doesn’t deserve. “Out there in the multiverse are two other dimensions where your parents are very close to developing Firebird technology. I would prefer that they didn’t.”

I fold my arms. “You mean you want to have all the power.”

“Who wouldn’t?” He shrugs. “Here’s how this is going to work. I have two dimensions working on Firebird research that need to be sabotaged as soon as possible. The next two splinters of Paul’s soul are hidden in those dimensions.” Conley’s thin fingers point at my own Firebird locket. “If you allow it, I can program your Firebird. You’ll receive the coordinates for the first of those dimensions—as well as a program you can use as a computer virus to destroy your parents’ research and your most valuable hardware.”

“How do I collect each splinter?” I clutch the spare Firebird more tightly. “The same way I’d give him a reminder? Just hold it against him, hit the combination on the locket?”

“Exactly. See? Easy as pie.”

Someday, when I have the luxury, I’m going to punch Wyatt Conley in the face. Hard.

Oblivious to my anger—or amused by it—Conley continues, “Collecting the second splinter of Paul’s soul will unlock the coordinates for the next dimension I need you to sabotage. Lather, rinse, repeat. Once you’ve done what I need you to do in each dimension, and gathered those two splinters, then you’ll come to the home office. Coordinates will be programmed into your Firebird with the rest.”

“The home office?” He must mean the Triadverse. “I don’t want to go there.”

“I have to check your work. When I go through your Firebird data, I’ll know whether you deployed the virus. If you’ve been a good girl—”

If there is any phrase I hate more than “good girl,” I don’t know what it is, and the words sound even more loathsome coming from Conley.

“—and you’ve stalled those dimensions’ research for a while, I’ll give you both the formula for Theo’s treatment and the coordinates for the final splinter of Paul’s soul. That final splinter is my insurance, you see. Your job is quite simple.”

Like it would ever be “simple” for me to betray my parents, much less while I’m afraid for both Paul’s and Theo’s lives. “You could have sent anyone to be your saboteur, or gone yourself.”

“There are dimensions where my reach is . . . limited.” It seems to gall Conley that he has to admit that he’s not omnipotent. “And yes, I could send certain other emissaries, but in order to do the kind of tricky work I’m looking for, they’d have to take Nightthief for a very, very long time. You know what that does to people now, don’t you?”

I remember Theo thrashing on our deck, body in spasm, skin pale. “Yes, I do.”

“We didn’t expect this one side effect. See, after a while, exposure to Nightthief takes away your ability to dream—hence the name. Sleep researchers still aren’t sure exactly why the ability to dream is so vitally important, but it is. Once you’ve lost it . . . let’s say mental processes start to break down rapidly, and dramatically.”

There’s something uniquely cruel about Theo dying because Wyatt Conley will no longer let him dream.

“As for the physiological damage—well, I don’t have to fill you in on that, do I? You’ve found out for yourself what Nightthief does to the lungs, the muscles, et cetera. But don’t worry about that. The lack of REM sleep will kill Theo before any of the rest progresses much further.” Conley smiles, though I don’t know what he thinks is so funny. I imagine taking one of the swords from the castle guards outside and stabbing it straight into his gut. He continues, “So, to sum up, do these errands for me, and in return, you get not one but two grand prizes. Once you report in to the home office, I’ll give you the formula for a solution that should ease Theo’s symptoms, maybe even reverse them.”

“That doesn’t sound like a cure.” If Conley intends to keep Theo sick—use him as a kind of hostage—I swear I’ll go for one of the swords right now.

Instead, Conley becomes serious and—possibly—sincere. “Marguerite, this is the best we have. If I could cure Nightthief exposure quickly, I wouldn’t need you, would I? But this treatment gives him a chance to heal. Keep treating him, and eventually, his body’s immune system should take care of the rest.”

Should. Not will. Still, I believe he’s telling the truth, only because he really wouldn’t need me if he had a cure.

Even more earnestly, Conley says, “And at the home office, I’ll also give you the coordinates for the final splinter of Paul’s soul—for the universe where you can put him together again. No errands to run there; that dimension isn’t one of my problems. You can just go get Paul and bring him home. Sound good?”

I imagine reawakening Paul, holding him in my arms, and telling him I’ll never let him go. I need that even more than Conley will guess—more than I can ever let him know. “It sounds . . . necessary.”

There’s that smirk again. “Is that a yes?”

Someday, I’m going to make Wyatt Conley sorry he ever screwed around with us. For now I have to play along. “Yes. Now give me what I need to get the job done.”

He holds out his hands to gesture at the stone walls and flaming torches. “I’ll give you the data, but I need a little more sophisticated setup than this. Shall we return to your home turf? I can transmit the first coordinates from there.”

My dimension, he means. I’m relieved to hear him suggest it. Mom and Dad deserve to know what’s going on. By now they must be frantic. “Okay.”

Conley takes his own Firebird from the collar of his robe. With its intricate design and dull bronze color, his Firebird looks . . . mysterious. More antique than cutting edge. It seems to belong to this dimension more than our own. “Shall we?”

“I want to say goodbye to Paul. This Paul.”

“You get so sentimental about the duplicates,” Conley says, shaking his head. “But I won’t tease you about it. My other self is just as bad.”

That’s definitely not the vibe I’ve gotten from our world’s Conley, but whatever. “Besides, you need to give that order protecting my parents. From the ‘witchcraft’ mobs. Right?”

“Oh, right! You got it.” He thumps the side of his head, like Duh. “I’ll talk to Her Holiness right away. Pope Martha the Third. Rumor has it she puts our Borgias to shame.” As he begins to walk away, Conley adds, “Listen, someday, when you’re on board with this and we’ve been working together for a while, you and I will look back on this and laugh.”

I don’t dignify that with an answer. Instead, I wait for him to leave, and then search for Father Paul.

As I guessed, he’s been waiting. Paul kneels in a small room off to the side that turns out to be a private chapel. A mural of Jesus raising Lazarus covers one wall, perspective wonky and faces stylized—the art, too, looks older than the Renaissance. They haven’t rediscovered the techniques of the ancient world yet; this civilization is still crawling away from the Dark Ages. Light flickers from a handful of tallow candles in iron stands. Paul—Father Paul—is praying, but when I walk in he quickly murmurs something in Latin, crosses himself, and turns his face to me. “Is everything well? The cardinal will take care of your family?”

“I hope so.” This chapel has no pews, only kneelers. So I go to my knees beside him; it’s the only way to be close enough.

Paul glances at the doorway, no doubt worried we’ll be seen. “You could claim sanctuary here. The sisters would keep you safe until your parents fall under the cardinal’s protection.”

Nuns? I’ll be spending the night in a convent? This world’s Marguerite doesn’t get to have nearly enough fun.

She’ll be near her Paul, though. That’s enough. All I want now is to be back with mine.

I bring my hand to Paul’s face and brush my fingers along his cheek. He draws in a sharp breath. Have they even kissed? Paul tentatively covers my hand with his, so that I’m cradling the side of his face. If I were to kiss him right now, he wouldn’t resist. He’d kiss me back so passionately that—well, this chapel might be deconsecrated.

But I stole the Grand Duchess Marguerite’s first and only night with Lieutenant Markov. I won’t steal any more firsts with Paul. Each me should get to experience that moment.

“Everything’s going to be all right,” I say, to myself as much as to him. “You and I—we’ll figure it out.”

“Ours is not an easy path.”

Paul’s old-fashioned, elegant phrasing reminds me of Lieutenant Markov, which reminds me of falling in love with Paul in the first place, and now I can’t take it anymore. I have to go home; the journey to save my Paul has to begin.

“The path isn’t easy,” I tell him. “But we’re walking it together.”

It’s true in every world, everywhere. I have to believe that.

I take hold of my Firebird and Paul’s—the two of them around my neck, one of them carrying a splinter of Paul’s soul—and leap back home.

I fully expected my parents to freak out about what Wyatt Conley had done and the bargain we’d struck. What I didn’t expect is that they would flat-out refuse to let me go.

“Dad—” I pull my hair back with both hands, trying to calm myself. “You know we don’t have any other choice.”

“We don’t know that,” Dad insists. “We have to at least try to get Paul out of this ourselves. We tracked him to the—Medievalverse, didn’t we? So we could figure out a way to trace the other splinters. We don’t need Conley’s bloody coordinates.”

“We already have the coordinates.” Theo sits on the sofa in a plaid shirt and jeans, a pale shadow of his usual self. His plastic hospital bracelet still hangs around one wrist. “Why wouldn’t we use them?”

The data packet arrived from Triad Corporation a couple of hours ago, just after I returned. While we can already see the first coordinates, the ones that will lead us to the second two dimensions have to be “unlocked”—by storing data that proves I’ve done Conley’s dirty work. Each betrayal wins me one more dimension, one more piece of Paul’s soul.

My parents don’t even want to download the information into the Firebirds. Dad insists, “We can manage on our own.”

Theo groans. “Come on, Henry. We didn’t even know splintering was possible until a couple of days ago. Tracing those splinters in alternate dimensions? We could be months away from cracking that.”

“Or days,” Mom says. “The only reason we haven’t solved the puzzle is because we haven’t yet tried. Obviously our counterparts in another universe managed to master this; if they hadn’t, Conley wouldn’t have the technology to splinter Paul in the first place. What they did, we can do. We only need to begin.”

Dad nods, becoming encouraged. “And if Triad could think of a treatment for Theo’s condition, well, then, so can we.”

“We’re not physicians, Henry.” My mother glanced at the bottle of Nightthief on the shelves, the one they’d hardly begun to study. “Still, we must make an attempt. Obeying Conley has to be our last resort.”

“This is the last resort!” I don’t argue with my parents that much anymore, but right now I feel like I could scream. “Don’t you get it? Paul has been torn apart. If I don’t do this, we might never get him back. If even one of Paul’s other selves dies, then—then we’ve lost him forever.”

Mom’s expression is more sympathetic, but she still shakes her head. “That is a risk, yes. But a fairly remote one given his age and health.”

I remember Lieutenant Markov, bloodied and weak, dying in the Russian snow. “That depends on where he is. He could be somewhere dangerous; Conley would do that. You know he would.”

My parents exchange a look, and Dad sighs. “We’ll give it one week. If we can’t make substantive progress on finding Paul ourselves in that time, then—well, then we’ll consider it.”

Consider it?” How can they do this? I step away from them, hurt and confused.

“Enough of this,” Mom says sharply. “You know how much we love Paul. We loved him even before you did, if you’ll recall. We aren’t standing our ground because we don’t want to get him back as soon as possible. We’re doing this because the price of cooperating with Conley is too high.”

My father adds, “Conley has his hooks into Paul already. That doesn’t mean we should hand you over too.”

I close my eyes tightly until the wave of anger passes. “Dad—”

“This discussion is over.” Mom heads toward the rainbow table. “If we’re going to save Paul, we need to get started.”

Dad follows her, as does Theo. But when Theo walks past me, our eyes meet, and I realize he knows what I’m thinking. I expect him to rat me out to my parents—that’s what the Triadverse’s Theo would do. Instead, he sits down at the table, pretending he doesn’t understand what’s about to happen.

They work until almost midnight. By that point I’m lying in bed, twisted up in the sheets, unable to sleep. All I can think about is the last time Paul and I were alone together before Theo collapsed—the last moment our lives seemed normal.

We lay together on the narrow twin bed in his dorm room, my head pillowed on his chest. Soft classical music played from his phone deck, almost covering the noise from other grad students down the hall. His dorm room is as stark as any other cheap student housing, plus Paul isn’t the kind of guy who would fix it up even if he had the money. He owns this utilitarian navy-blue bedspread, and there’s only one piece of decoration on the walls.

Hanging above us that night was my portrait of Paul. Not the one I’m painting now, but the first one I ever attempted. I cut it to ribbons when I thought Paul had betrayed us and killed my father. To my surprise, Paul insisted on keeping it just as it is. It reminds me how close I came to losing you, he said. That’s the kind of thing I’d want to forget, but that he always wants to remember. At least he let me patch it up.

Paul stroked my hair, his fingers untangling my curls. It’s the gentlest, most comforting touch in the world. “I heard from a few more universities today, about my postdoc.”

One of the weird things about being a scientist is that you have to get multiple college degrees—and even after you get your PhD, you remain a student for another year or two, usually at a different college than the one you studied at before. The point of the whole postdoc thing? I have no idea. It’s a hoop they all have to jump through.

It would drive me crazy that Paul has to leave, if I weren’t headed to college myself in January. “Which ones?”

“Oxford made an offer; so did Stanford. I expect to hear from Cambridge and CERN soon.”

This is information that would make most people jump for joy. Paul takes it in stride, but my stomach knots. “Nothing from Harvard or MIT? Or maybe Princeton?”

“Not yet. MIT is a possibility, but—professors at Harvard and Princeton are skeptics.”

About Mom and Dad’s work, he meant. Those are the professors trying to tear them down, the ones who don’t believe us about what happened in December. “Okay, so, we think about MIT.”

His gray eyes met mine. “It doesn’t matter where I go. I’ll still be yours.”

I kissed him softly, enjoying the way we were tangled together, the soft sound of his jeans against mine as we shifted to get closer. “But I’d like it if you could be mine, like, every weekend. Not just at Christmas and spring break.”

What with all the craziness of December, I’d deferred starting college until next January. The Rhode Island School of Design had agreed to that; they preserved my scholarship and everything. January is when Paul’s likely to start his postdoc. If he goes to MIT, we won’t be far apart at all.

Paul said, “Are you still unwilling to apply to any schools besides RISD?”

“RISD’s the best in the country for art restoration.”

“What about fine art?” His thumb brushed along the line of my cheekbone. “Forget taking care of other people’s paintings. Create your own.”

“See, this is how I know you’re a genius in physics but not economics. Ever heard the phrase ‘starving artist’?”

“I doubt you would starve, as both your parents and I are gainfully employed.” Paul went from adorably literal to practical. “If you could study art anywhere in the world—to be an artist—where would you go? I’ve heard Josie tell you to think about the University of Chicago—”

“Not Chicago.” The words came out too easily, for something so hard for me to admit. “I mean, that’s a great school, but if I could go anywhere? I’d pick the Ruskin School of Fine Art, at Oxford.”

“Why Ruskin?”

“They teach everything there.” I couldn’t keep the envy from my voice. “You study anatomy as in-depth as medical students do, so you understand what’s under the skin of the people you’re trying to paint or sculpt. They have professors who teach just about every technique, ancient or modern or experimental. They’re better than anyone.”

“So go there,” said Paul the genius who has the world’s top physics departments fighting over him.

“I’d never get in. Remember, I haven’t even been to high school, really.” The downside of homeschooling: Colleges find it tougher to evaluate you. RISD got with the program, but a foreign university would probably find my record harder to assess.

Paul shook his head. “You’d get in when they saw your work. Oxford would admit you immediately.”

Would they? We both glanced up at the shredded portrait of Paul; his eyes stare from the portrait as intensely as in real life. Yet I couldn’t imagine the professors at the single best art school in the world would understand this painting in the same way. “The important thing is getting you into the right postdoc. I know that. You’re doing groundbreaking research. I’m just painting.”

“I’m just solving formulae. You’re creating works of art that might be meaningful long after my scientific work seems mundane.”

I laughed. “Not likely.”

“But possible. Your dreams are as important as anyone else’s. Your future is as important as mine. I’m willing to make compromises, if that’s what it takes for us to remain together—but we shouldn’t compromise before we even start.”

“It’s different for me,” I said. “I’m not brilliant like the rest of you.”

“You have no particular aptitude for science. But there are many kinds of intelligence. I’d never want to take your career as an artist away from you, any more than you would take my research from me.” Propping himself on one elbow, Paul looked down at me, almost grave. “Stop measuring yourself against us. It’s not the right scale. You have your own gifts, your own talents. Show the world everything you’re capable of, Marguerite. You don’t even see how amazing you are.”

There are moments when Paul’s awkwardness drops away and he suddenly says the exact right thing. Those moments make me feel like I’m melting—like we’re fusing together, ceasing to be two separate people, turning into one.

That night was one of those moments.

“Hey,” I said, more softly. “Mom and Dad are going to that conference in Tokyo in a couple of weeks. You’re not traveling with them, right?”

“We decided against it.”

“Well, then, maybe”—my cheeks flushed with heat—“maybe you could stay over.”

We could be alone in the house. Nowhere near family members who know way the hell too much about my love life already. Instead, we’d be together with absolutely nothing between us, all night long.

He looked at me for a long moment, eyes darkening in a way I remember from that night in the dacha with Lieutenant Markov. Slowly, he nodded. “Okay.”

I laughed softly, self-conscious. “It feels like we haven’t done this before.”

“We haven’t. Well. Not here.”

My Paul was only a sliver of consciousness within Lieutenant Markov that night in the Russiaverse, because he was separated from his Firebird and unable to receive any reminders. But he was there throughout that entire night—so he remembers having sex as vividly as I do. I said, “Does it still count as our first time? Since it’s just our first time in this dimension?”

He brushed his lips against my temple. “I guess it does.”

I slid atop him, my legs on either side of his hips. Paul’s hands caught me at my waist. When I leaned over him, my hair fell past my shoulders, and he shifted slightly beneath me, enjoying the feel of me above him. I couldn’t help imagining us just like this—without our clothes in the way.

Smiling, I teased, “You realize this means we’re going to lose our virginity to each other . . . twice.”

He thought about that for a moment before he started to grin too. “Our lives are strange.”

“Deeply weird,” I agreed, just before we kissed. Paul’s hands slipped beneath the hem of my shirt, slow and sure and hot.

We may not have spent the past months having sex, but that didn’t mean we hadn’t had fun. He knows how I kiss. I know how he touches me. We’ve learned each other inside and out.

And now I have to lie here in bed in the middle of the night, alone and terrified for Paul’s soul—until I’m 100 percent sure my parents are asleep.

By 2:00 a.m., I feel pretty sure Mom and Dad have drifted off, no matter how worried they are. So I get up, tiptoe into the living room in my T-shirt and leggings, and find Theo waiting for me.

He’s sitting at the rainbow table, all three working Firebirds lying in front of him. “I’ve been double-checking each one to make sure they’re operating normally,” he says. Theo picks up the one I took along for my Medievalverse rescue attempt, studying the sheen of the light against its coppery surface. Softly he adds, “Part of Paul’s soul is in this thing. Gotta make sure it keeps ticking, right?”

I nod. As worried as I am for Paul, as determined as I am to begin, I can’t help noticing how exhausted Theo looks. No doubt he told my parents he was going to bed right after them; instead, he sat up, waiting for me.

Then again, maybe sleep is meaningless for him now. “Theo—what Conley said about the dreams—you really haven’t had any?”

He remains bowed over his work. “I haven’t remembered any dreams in a while. Doesn’t necessarily mean anything. I don’t remember them often.” His dexterous hands hesitate, and I can sense him weighing his words. “Thanks for making me part of the deal, by the way.”

“What do you mean?”

“Telling Conley you wanted a cure for me.”

“Paul’s the one who risked everything for you.”

“And I intend to thank him too, once we’ve got him back. But right now, I’m thanking you.” The brighter light he’s aimed at the Firebird silhouettes Theo’s face, and the starker lines reveal that he’s lost weight. It’s not like I never noticed before, but I thought it was the usual grad-student grind. Now I realize Theo’s been fading away. “Sometimes I’ve wondered if you’d ever fully trust me again. Then you stood up for me. Put it all on the line. It was . . . Marguerite . . . you know, let’s stick with thanks.”

I don’t know what to say, so I nod. His eyes meet mine, only for a moment, before he turns back to the Firebird, nods in satisfaction, and snaps it shut again. “They’re ready?” I ask.

“Ready as they’re ever going to be.”

“No point in waiting around until Mom and Dad wake up.” They’d stop me from doing this if they knew, even if it meant locking me in my room or smashing the Firebirds to gold dust. “I should go.”

Theo says, “Correction. We should go.”

“We?” I know I heard him right, but it takes a minute to wrap my head around it. “Conley didn’t say anything about you coming along.”

“He didn’t say I had to stay home, either.” Theo’s grin is sharp enough to cut.

I’m still in shock. “You said—you said you weren’t ever going to travel through the dimensions.”

“That was before they kidnapped my little brother.”

The old nickname—and a reminder that Theo’s not doing this for me. He didn’t even mention saving his own life. Only Paul’s.

Yet I can’t help recalling what Theo said to me. Apparently, when I get a little bit of power, it goes to my head. He sees traveling as a temptation, and Theo’s not good at resisting temptation.

Still, if he’s willing to take this chance for Paul, I have to be willing to take a chance on him.

“All right,” I say. “Let’s go.”

We walk together to my room, where I’ve already posted a KEEP OUT note; my parents will understand the need to keep the room clear for Theo and me to return—if and when we can. I slide two of the Firebirds around my neck, mine and Paul’s; though I know it’s only my imagination, I can’t help thinking Paul’s feels heavier. I remember the Enlightenment scientists who tried to determine the weight of one soul. Now I could tell them.

Theo takes the last Firebird in hand. He stares at it for a moment. Takes a deep breath. Then puts it around his neck—ready for the journey at last.

“Okay?” I say to Theo.

His old bravado returns. “Let’s blow this Popsicle stand.”

My hand closes around my Firebird—the world falls away—

—and I slam into my other self.

This time I’m in bed—definitely one of the better places to arrive in a new dimension. The room is dark, so I can’t really get a look at much. Mostly I just notice that I’m stark naked. Okay, whoever I am in this dimension, I sleep in the nude.

Except . . . I’m breathing hard. My skin is slightly sweaty. I feel faint scrapes along my throat and breasts and thighs—those could be from fingers, or teeth. And there’s a pleasant kind of soreness that tells me this Marguerite just had sex. As in, not even two minutes ago.

I turn my head toward the naked man lying next to me—and see Theo.
