FINALLY, THE WEATHER became warm enough for them to start having their classes outside almost daily. One bright afternoon, Call and Tamara were sent to the edge of the woods to study with Master Milagros’s class while Rufus took Aaron for special training.

They didn’t go far from the Magisterium gates, but enough greenery had sprung up to block most of the cave entrance from view. The warm air smelled of the rosemary, valerian, and deadly nightshade that grew on the grounds, and there was a rapidly growing pile of light jackets and coats on the ground as the apprentices dashed around in the sunlight, playing catch with balls of fire, using air to control the way they moved.

Call and Tamara joined in with enthusiasm. It was fun, focusing on lifting a flaming orb, then rocketing it between hands. Call strained to get it close enough to his palms so that it almost touched but didn’t quite. Gwenda had burned herself once and was now being extra careful; her ball of fire hovered more than moved. Although Call and Tamara had come late, the exercise was enough like ones Master Rufus had made them practice — particularly the sand exercises, which were forever burned into their minds — that they were able to get the hang of it quickly.

“Very good,” Master Milagros said, walking between them. She’d taken off her shoes and sloughed off her black uniform shirt, revealing a T-shirt with a rainbow on the front. “Now I want you to create two balls. Split your focus.”

Call and Tamara nodded. Splitting their focus was second nature, but some of the others were struggling. Celia managed it, as did Gwenda, but one of Jasper’s orbs popped, singeing his hair.

Call snickered, earning a dark look.

Soon, though, everyone was tossing two and then three balls of fire into the air, not quite juggling but something that might have approximated a slow-motion version of it. After a few minutes of that, Master Milagros stopped them again.

“Please choose a partner,” she said. “The apprentice without a partner will practice with me. We’re going to toss our ball to our partner and catch the ball our partner tosses to us. So extinguish all balls in your hands but one. Ready?”

Celia tapped Call’s sleeve shyly. “Practice with me?” she asked. Tamara sighed and went to practice with Gwenda, leaving Jasper to partner with Master Milagros, since Drew had complained of a sore throat and stayed in his room. Back and forth the fire went, searing through the lazy springtime air.

“You’re really good at this!” Celia said, beaming, as Call made the fire do a loop-the-loop before dropping it just above her hands. Celia was the sort of friendly person who handed out compliments easily, but it was still nice to hear — even if Tamara was rolling her eyes behind Celia’s back.

“All right!” Master Milagros clapped her hands to get everyone’s attention. She looked a little disgruntled — there was a burn in her sleeve where Jasper must have thrown a fireball too close. “Now that you all are used to using air and fire together, let’s add something even more difficult. Come this way.”

Master Milagros led them down the hill to a stream that bubbled over rocks. Four thick oak logs bobbed in the water, clearly magicked to stay in place, since the current flowed around them. She pointed to the logs. “You will climb onto one of those,” she said. “I want you to use water and earth to balance yourself there, while keeping at least three fire orbs in the air.”

There was a murmur of protest, and Master Milagros smiled. “I’m sure you can do it,” she said, shooing the students toward a log. As Call moved forward, she put a hand on his shoulder. “Call, I’m sorry, but I think you better stay here. With your leg, I don’t think it’s safe for you to do this exercise,” she said quietly. “I’ve been thinking about a version that could suit you better. Let me get the others started and I’ll tell you about it.”

Jasper, passing by on his way to the stream, looked over his shoulder and smirked.

Call felt a dull red fury bubble up in his stomach. Suddenly, he was back in gym class in sixth grade, sitting on the bleachers while everyone else climbed ropes, or dribbled basketballs, or bounced up and down on the mats.

“I can do it,” he told her.

Master Milagros stepped toward the bank of the stream, her bare feet sinking in the mud. She smiled. “I know, Call, but the exercise is going to be very difficult for all the apprentices and it would be even harder for you. I think it’s more than you’re ready for.”

So Call watched as the other apprentices waded or clumsily levitated to their logs, wobbling as Master Milagros released the magic that had been holding the wood in place. He could see the strain on their faces as they tried to move the log against the current, stay standing, and levitate a ball of fire. Celia fell almost immediately, hitting the stream, soaking her uniform — and laughing all the while. It was a hot day and Call bet splashing in the water felt pretty good.

Jasper, surprisingly, seemed good at the exercise. He managed to lever himself up on his log and stay standing as he conjured his first ball of fire. He tossed it between his hands, smirking at Call, making Call think of what he’d said in the Refectory.

If you could ever learn to levitate yourself, maybe you wouldn’t slow down your teammates so much, limping along after them.

Call was a better mage than Jasper; he knew he was. And he couldn’t stand that Jasper thought otherwise.

Giggling, Celia pulled herself back up onto her log, but her feet were wet, and she slipped off again almost immediately. She plunged back into the water and Call, seized by an impulse he couldn’t control, dashed forward and hopped up onto the abandoned log. After all, he’d skateboarded before — badly, he admitted. But he’d done that and he could do this.

“Call!” cried Master Milagros, but he was already halfway across the stream. It was much harder than it had looked from shore. The log rolled under his feet, and he had to throw his hands out, bracing himself with earth magic, to keep his balance.

Celia surfaced in front of him, tossing back her wet hair. Seeing Call, she gasped. Call was so startled that his magic deserted him. The log rolled forward, Celia dove for the the bank with a little shriek, and Call’s bad leg went out from under him. He pitched forward and landed in the water.

The stream was black, icy cold, and deeper than he’d imagined. Call twisted around, trying to swim for the surface, but his foot was wedged between two stones. He kicked desperately, but his bad leg wasn’t strong enough to free the good one. Pain shot up his side as he tried to pull himself free, and he screamed — silently, underwater, bubbles escaping his lips.

Suddenly, there was a hand circling his upper arm, pulling him up. There was more pain as his foot pulled free from the streambed, and then he was out of the water, gasping. The person who’d grabbed him was splashing through the stream, and Call could hear the other apprentices yelling and calling out as he was tossed onto the bank, coughing and spitting water.

He looked up and saw angry brown eyes and dripping-wet black hair.

“Jasper?” Call said in disbelief, then coughed again, bringing up a mouthful of water. He was about to turn aside and spit it out, when Tamara suddenly appeared, dropping down next to him on her knees.

“Call? Call, are you okay?”

Call swallowed the water, hoping it didn’t have tadpoles in it. “Fine,” he croaked.

“Why did you have to show off like that?” Tamara asked angrily. “Why are boys always so dumb? After Master Milagros specifically told you not to! If it hadn’t been for Jasper —”

“He’d be fish food,” Jasper said, squeezing water out of a corner of his uniform.

“Well, I wouldn’t go quite that far,” said Master Milagros. “But, Call, that was very, very foolish.”

Call looked down at himself. One of his pants legs was torn, his shoe was missing, and blood trickled down his ankle. At least it was his good leg, he thought, so no one could see the twisted-up mess his other one was. “I know,” he said.

Master Milagros sighed. “Can you stand?”

Call tried to rise to his feet. Instantly, Tamara was next to him, offering an arm to lean on. He took it, straightened — and yelped as pain shot through him. His right leg felt as if someone had shoved a knife into his ankle: a hot, sickening pain.

Master Milagros bent down and touched cool fingers to Call’s ankle. “Not broken, but a bad sprain,” she said after a moment. She sighed again. “Class is over for the afternoon. Call, let’s get you to the Infirmary.”

The Infirmary turned out to be a large, high-ceilinged room entirely free of stalagmites, stalactites, or anything that bubbled, dripped, or smoked. There were long lines of beds, made up with white sheets, arranged as though the Masters expected a large quantity of wounded children might be brought there any minute. At the moment, there was nobody but Call.

The mage in charge was a tall red-haired woman who had a snake curled around her shoulders. Its pattern changed as it moved, turning from leopard spots to tiger stripes to wobbly pink dots. “Put him over there,” the woman said, pointing grandly as the apprentices carried Call in on a stretcher made of branches, which Master Milagros had created. If Call’s leg hadn’t hurt so much, it would have been interesting to watch her use earth magic to snap the branches together and bind them with long, flexible roots.

Master Milagros supervised as they deposited Call on a bed. “Thank you, students,” she said as Tamara hovered anxiously. “Now let’s go and let Master Amaranth get to work.”

Call propped himself up on his elbows, ignoring the shooting pain in his leg. “Tamara —”

“What?” She turned around, dark eyes wide. Everyone was looking at them. Call tried to communicate with her with his eyes. Look after Havoc. Make sure he gets enough food.

“He’s going cross-eyed,” Tamara said to Master Amaranth worriedly. “It must be the pain. Can’t you do anything?”

“Not with all of you here. Shoo! Shoo!” Amaranth waved a hand, and the apprentices hurried out with Master Milagros, Tamara pausing in the doorway to shoot another worried look at Call.

Call flopped back onto the bed, his mind on Havoc, as Master Amaranth cut away his uniform, showing purple bruising down the expanse of his leg. His good leg. For a moment, panic rose in his chest, making him feel as though he was choking. What if he’d managed to make it so that he couldn’t walk at all?

The Master must have seen some of the fear in his expression because she smiled, taking a roll of moss out of a glass jar. “You’re going to be fine, Callum Hunt. I’ve fixed worse injuries than this.”

“So it’s not as bad as it looks?” Call ventured.

“Oh, no,” she told him. “It’s just as bad as it looks. But I’m very, very good at my job.”

Somewhat comforted and deciding he’d be better off not asking any more questions, Call let her cover his leg in bright green moss and then pack the whole thing with mud. Finally, she gave him a drink of some milky liquid that took away most of the pain and made him feel a bit like he was floating up toward the ceiling of the cave, as though the wyvern breath had hit him after all.

Feeling very foolish, Call slipped off to sleep.

“Call,” a girl whispered, very close to his ear, making his hair move and tickle his neck. “Call, wake up.”

Then another voice. A boy’s voice this time. “Maybe we should come back. I mean — doesn’t sleep help healing or something?”

“Yeah, but it doesn’t help us,” the first voice said again, louder this time, and grumpier. Tamara. Call opened his eyes.

Tamara and Aaron were there, Tamara seated beside him on the bed, gently shaking his shoulder. Aaron held up a drooling, panting, tail-wagging Havoc. He had a makeshift rope leash around his neck.

“I was going to walk him,” Aaron said. “But since there’s no one but you in the Infirmary, we thought we’d bring him for a visit first.”

“We brought you some dinner from the Refectory, too,” Tamara said, pointing at a napkin-covered plate on the nightstand. “How are you doing?”

Call moved his leg experimentally, within the mud cast. It didn’t really hurt anymore. “I feel like a moron.”

“It wasn’t your fault,” Aaron said at the same time that Tamara said, “Well, you should.”

They looked at each other, and then at Call.

“Sorry, Call, but it wasn’t your best idea,” Tamara said. “And you totally stole Celia’s log. Not that she won’t liiiiiike you anyway.”

“What? She doesn’t,” Call protested, horrified.

“Does, too.” Tamara grinned. “You could hit her on the head with a log and she’d still be all Call, you’re so good at this magic stuff.” She looked over at Aaron, who had an expression on his face that told Call he agreed with Tamara and thought it was hilarious.

“Anyway,” Tamara said, “we just don’t want you to get crushed under a log. We need you.”

“That’s right,” Aaron agreed. “You’re my counterweight, remember?”

“Only because he volunteered first,” Tamara said. “You should have held auditions.” Call had been worried that Tamara might be jealous when she found out Aaron had picked Call as his counterweight, but mostly she just seemed to think that, as much as she liked Call, Aaron could probably have aimed higher. “I bet Alex Strike is still available. He’s cute, too.”

“Whatever,” said Aaron, rolling his eyes. “I didn’t want Alex. I wanted Call.”

“I know,” Tamara said. “He’ll be good at it,” she added unexpectedly, and Call flashed them a grateful smile. Even flat on his back with his leg wrapped in mud, it felt good to have friends.

“And here I was worried you were going to forget about Havoc,” Call said.

“No chance of that,” said Aaron cheerfully. “He ate Tamara’s boots.”

“My favorite boots.” Tamara swatted lightly at Havoc, who dodged away, scooted toward the door, and looked pitifully back at Call in the bed. A small whine rose from his throat.

“I think he wants to go for his walk now,” Call said.

“I’ll take him.” Aaron jogged over to the door and looped the free end of the rope around his wrist. “No one’s in the corridors right now because it’s dinnertime. I’ll be right back.”

“If you get caught, we’ll pretend we don’t know you!” Tamara called good-naturedly as the door swung shut behind him. She reached for the plate on Call’s nightstand and yanked off the napkin. “Yummy lichen,” she said, balancing the plate on Call’s stomach. “Your favorite kind.”

Call picked up a dried vegetable chip and bit into it thoughtfully. “I wonder if we’re going to all be so used to lichen that when we get back home, we won’t want pizza or ice cream. I’ll wind up in the woods, eating moss.”

“Everyone in your town will think you’re crazy.”

“Everyone in my town already thinks I’m crazy.”

Tamara pulled one of her braids around and fingered the end of it thoughtfully. “Are you going to be okay going home for the summer?”

Call looked up from his lichen. “What do you mean?”

“Your father,” she said. “He hates the Magisterium so much, but you — you don’t. At least I don’t think you do. And you’re going to come back next year. Isn’t that exactly what he didn’t want?”

Call didn’t say anything.

“You are coming back next year, aren’t you?” She leaned forward, worried. “Call?”

“I want to,” he burst out. “I want to, but I’m afraid he won’t let me. And maybe there’s a reason he won’t — but I don’t want to know it. If there’s something wrong with me, I want Alastair to keep it to himself.”

“There’s nothing wrong with you except that you broke your leg,” said Tamara, but she still looked anxious.

“And I’m a show-off,” Call said, trying to lighten the mood.

Tamara threw a piece of lichen at him and they talked for a while about how everyone was reacting to Aaron’s new celebrity status — including Aaron. Tamara was concerned about him, but Call assured her Aaron could handle it.

Then Tamara started to tell him about how excited her parents were to have her in the same group with the Makar, which was good, because she wanted them to be proud of her, and bad, because it meant they were even more concerned than usual that she behave in an exemplary manner at all times. And their idea of exemplary didn’t always match up with hers.

“Now that there’s a Makar, what does it mean for the Treaty?” Call asked, thinking of Rufus’s speech and the way the Assembly members had reacted to it at the meeting.

“Nothing right now,” Tamara said. “No one would want to move against the Enemy of Death while Aaron is so young — well, almost nobody. But once the Enemy hears about him, if he hasn’t already, who knows what he’ll do.”

After a few minutes of talking, Tamara glanced at her watch. “Aaron’s been gone a long time,” she said. “If he’s out there any longer, dinner will be over, and he’ll get caught coming back through the corridors. Maybe I should go check on him.”

“Right,” said Call. “I’ll go with you.”

“Is that a good idea?” Tamara raised an eyebrow, looking at his leg. It did seem pretty bad, wrapped up in moss and sealed with mud. Call wiggled his toes experimentally. Nothing hurt.

Call swung his legs over the side of the bed, sending splintering cracks through his mud-moss cast. “I can’t sit here any longer. I’m going stir-crazy. And my leg itches. I want to get some air.”

“Okay, but we’re going to have to go slow. And if anything hurts, you’ve got to rest and then go right back.”

Call nodded. He pulled himself to his feet using the bedpost. As soon as he was standing, the cast broke completely in half and fell away, leaving his calf bare under his sliced-up pants leg.

“That’s a good look for you,” said Tamara, heading for the door. Call quickly yanked on his socks and boots, which had been shoved under his bed. He tucked the individual pieces of his pants into his socks so they wouldn’t be flapping around, and picked up Miri, sliding her through his belt. Then he followed Tamara out into the hall.

The corridors were quiet, as the students were all in the Refectory. Call and Tamara tried to make as little noise as possible as they made their way to the Mission Gate. Call felt wobbly. Both his legs hurt a little, although he wasn’t going to tell Tamara that. He thought he must look pretty bizarre, with his pants cut open from the knee down and his hair sticking up all over the place, but fortunately, there was no one to see him. They found the Mission Gate and slipped silently out into the darkness.

The night was warm and clear, the moon out, outlining the trees and the paths around the Magisterium. “Aaron!” Tamara called in a low voice. “Aaron, where are you?”

Call turned around, scanning the woods. There was something a little creepy about them, the shadows thick between the trees, the branches rattling in the wind. “Havoc!” he called.

There was a silence, and then Havoc burst out from between the trees, coruscating eyes whirling like fireworks. He dashed up to Call and Tamara, his makeshift rope-leash dragging on the ground behind him. Call heard Tamara give a little gasp.

“Where’s Aaron?” she asked.

Havoc whimpered and reared up, pawing at the air. He was practically vibrating all over, his fur standing up, his ears swiveling wildly. He whined and danced toward Call, pushing his cold nose into Call’s hand.

“Havoc.” Call dug his fingers into the wolf’s ruff, trying to get him to calm down. “Are you all right, boy?”

Havoc whined again and danced away, wriggling out of Call’s grasp. He jogged toward the forest, then paused and looked over his shoulder at them.

“He wants us to follow,” said Call.

“Do you think Aaron is hurt?” Tamara asked, looking around wildly. “Could an elemental have attacked him?”

“Come on,” Call said, starting across the dark ground, ignoring the twinge in his legs.

Havoc, assured that they were behind him, raced off like a shot, darting between trees like a brown blur in the moonlight.

As fast as they could go, Tamara and Call followed.
