“I have to shut this down!”

Spencer staggered to his feet, rage and fear coursing through him. His razorblade slashed in utter frustration, cutting asunder a pack of agitated Filths. He reached the lagoon’s embankment and fell to his knees, peering over the edge for any sign of his friend.

“Phew,” Daisy said, staring up at him. “That was close.”

She had fallen into one of the blue recycle boats. Still tethered to the bank, it bobbed against the current of the draining Glop.

“I think it’s some kind of boat,” Daisy said. She reached down and picked up the bristly toilet brush. “What’s this for? Is this what they use to destroy the Glop?”

But the Aurans weren’t destroying it. The Glop was being recycled, flushed downward to an unknown source.

Spencer squinted across the glowing haze of the lagoon toward the pump house. He needed to stop the recycling process. Maybe he could turn off the pump before any more Glop was drained.

Making a hasty decision, Spencer slid off the muddy bank and dropped into the boat next to Daisy. Rho had said that it was too dangerous to sail while the pump was activated. But they would never make it to the pump house on foot, not with so many enemies between them and their destination.

“We have to get to the far side of the lagoon,” Spencer said. “The Aurans are recycling this Glop, and that’s going to make more Toxites. I think I can shut it down if we can get inside that pump house.”

Spencer swung his razorblade and sliced through the tethering rope. Instantly, the current pulled them away from the bank. Daisy lowered herself to the bottom of the boat as Spencer took the toilet brush from her hand.

Reaching off the back of the recycle bin, he dipped the brush into the thick liquid. The brush spun, kicking up gooey bubbles as it propelled them farther into the lagoon.

There was a shout from the bank, and Spencer took a hasty glance over his shoulder in time to see V sliding down into another boat. She wasn’t going to let Spencer escape, even if it meant abandoning the fight for a high-speed boat chase.

“They’re after us!” Daisy shouted as V cut her boat free and dipped the brush into the Glop.

Spencer and Daisy were halfway to the pump house when their recycle bin caught a swift eddy. The boat lurched and spun, rocking almost to the point of throwing them out. Spencer dug the toilet brush deeper into the Glop. It was spinning hard, flinging out a wake of sticky liquid, but the boat wasn’t going anywhere.

V sped forward, hunched over the blue bin. Her silvery hair blew like a mad scientist’s as her boat skipped off waves.

“I thought we were supposed to go that way!” Daisy pointed as their boat dragged backward.

“We’re caught in a whirlpool!” Spencer frantically shifted the toilet brush from side to side. “It’s sucking us down!”

He abandoned the brush, dropping it into the bottom of the boat. They were twirling in circles now, drawing closer to the Broomstaff island, though both were too dizzy and sick to realize just how close.

Daisy’s eyes were wide as she stared into the churning muck. “Do you think this is what happened to the Titanic?” she asked. “Maybe we should abandon ship and try to swim to shore.”

“I don’t think we can even survive in Glop,” Spencer answered, “let alone swim!”

Then suddenly, mop strings lashed out through the darkness, snaring Spencer around the middle. He would have been jerked out of the boat if his grip hadn’t been so solid on the edge of the bin. As it was, his arms felt like they were getting ripped from their sockets.

The mop strings stopped the blue boat from spinning, and Spencer saw that the weapon extended not from V, as he’d expected, but from the Broomstaff island.

Rho held the handle of the mop, bracing herself in the slippery mud. The girl heaved backward, and Spencer felt like he might rip in half. After another heave, the mop strings began to retract naturally, dragging the blue bin out of the dangerous whirlpool and back into calmer waters.

In the next moment, the strings were gone altogether and Spencer tumbled forward onto Daisy. She gave a nervous laugh and reached over the back of the bin, toilet brush in hand. The bristles spun into action, sending them back on course for the pump house.

Rho gave an encouraging wave, and Spencer managed to return the gesture before he saw the incoming boat.

V was closing fast. She had carefully avoided the whirlpool and gained a big advantage. V maneuvered the craft to cut them off, positioning her bin between Spencer and the pump house.

“Dig deep!” Spencer called to Daisy. The girl gritted her teeth and plunged the brush deeper into the Glop, so deep that the heat began to scald her bare hand. The blue bin responded immediately, gathering speed on what seemed like a collision course with V.

Spencer unclipped a broom, rising unsteadily to his feet and taking aim. Dead ahead, the leader of the Aurans scowled at him.

When Spencer was close enough to see her rain-soaked face clearly, he gauged the distance to the pump house, hoping he was close enough. Then he reached back, grabbed Daisy by the arm, and slammed the broom against the bottom of the blue bin boat.

They launched forward, Daisy screaming, then grabbing onto Spencer’s back as they soared over V’s head. Their empty bin capsized with the shaky launch, sinking out of sight and melting into a streak of blue plastic.

Spencer and Daisy barely reached the shore. They skidded through the mud, broom flying aside as they bumped painfully against the wall of the pump house. Spencer was immediately on his feet. Daisy, slightly stricken, took a second longer. By the time she was up, Spencer had already found the door.

It was a simple brick building, showing signs of decay and erosion that suggested it was quite old. The door was wooden and warped, with bands of iron holding it together. Spencer grabbed the handle and pulled. The door was stiff, but in a moment, the two kids stood on a landing inside the pump house.

The inside was bigger than Spencer expected, with a ladder leading down and another shorter one leading up to a loft. Giant pipes intersected the whole house, twisting and turning in every conceivable angle. The pipes vibrated under the pressure of operation, the joints rattling like they might shake apart at any moment.

At the center of the room was a massive hydraulic pump. The huge cylinder lifted smoothly on an oiled shaft, then slammed down hard, releasing a hiss of sulfuric vapor as it forced the Glop through the pipes and deep into the earth.

“It smells funny in here,” Daisy said, crinkling her nose. Spencer couldn’t let himself get distracted by gross details.

“There’s got to be a switch or something to turn this thing off,” he said.

“Maybe up there.” Daisy pointed up to the loft.

Spencer nodded. “You check above; I’m going down for a look around.”

They tightened their janitorial belts, and Daisy quickly scampered up the short ladder while Spencer began his descent down the long one.

“It just looks like a bunch of gears and pulleys up here!” Daisy shouted before Spencer had even reached the bottom of his ladder. “My dad would love this place.”

“Look for a button or a switch!”

Spencer skipped the bottom rung of the ladder and landed on the concrete floor. Here the vapor was thicker, a sickly yellow hue that forced him to squint. He ducked under some pipes and made his way toward the rising and falling pump. He noticed a set of meters and gauges, red needles that spun around, measuring volume and pressure.

“Nothing up here!” Daisy shouted, her voice almost lost in the hiss of the great pump.

“We have to find it!” Spencer called back, running his hands over the meters for any kind of button. “We have to shut this thing down before all the Glop gets recycled!”

“Too late for that!” called a familiar voice.

Spencer whirled around, peering through the hazy vapor to see V standing on the platform above. Daisy was halfway down the ladder. Before she could move, V was on her, pinning the girl against the rungs and holding her fast.

“Come up here, Spencer,” V said, “so we can talk about this.”

“Spencer! Don’t!” Daisy shouted, but V clamped a hand over her mouth.

“I have to shut this down!” Spencer called.

“It’s too late. The pump can’t be stopped once it’s started. The Glop must be recycled,” V said. “Circle of life.”

Spencer gritted his teeth. “You don’t know what you’re doing!” he said. “Toxites are born in Glop! You’re just making more monsters!”

“Why is that my problem?”

“You’re destroying education!”

V shrugged. “I’m just keeping things the way they were when the Founding Witches left.”

“That’s wrong,” Spencer muttered, hardly loud enough for her to hear. “The Witches wouldn’t want this.” He raised his voice defiantly. “You’re out of line, V! And I have to stop you!”

There was only one thing left to do. Lifting one hand in front of his face, Spencer braced himself and spat onto his palm. His hands came together with a resounding clap as he rubbed them briskly together.

His hands were glowing now, fists of golden fire that caused V to release Daisy and step away in fear.

Then Spencer reached out his left hand and pressed it against the rising pump.
