They were on a direct course for the top of the castle.

In the next instant, a million thoughts seemed to flow through Tick’s mind, processing and reprocessing.

A few months ago, he’d made a very difficult decision. Even though his life had become frightening—just as Master George had promised it would—and even though he could’ve made it all go away with a simple toss of the first letter into the fire, he hadn’t done it. Some courage he didn’t know he’d had, some sense of duty and right he didn’t know was so powerful, had swelled inside his heart and given him the conviction to make an extremely hard choice. He remembered thinking of his little sister Kayla, and what he might do if her life were at stake.

And now, truly for the first time in his existence, Tick had a chance to risk his own life to save another.

The question posed by Master George so long ago popped back into his mind.

Will you have the courage to choose the difficult path?

Tick screamed Sato’s name and slammed the handlebars up and forward, bulleting the Windbike in a straight path toward the fangen. Toward Sato.

Sofia continued to fly the Windbike as crazy as she dared, swerving and diving and skyrocketing upward in an attempt to evade the countless creatures coming after them. Her head hurt from the effort; her stomach begged her to stop.

Behind her, Paul continued to shoot as many fangen as he could with his Sound Slicer, defending her as she drove. He’d slipped and almost fallen several times, but she had no choice but to keep flying forward.

She caught a glimpse of Tick streaking past her on his Windbike.

Alone.

Where was—

Before she could finish her thought, one of the flying creatures slammed into them from the side, driving its head into the engine of the bike. Sofia lurched, barely hanging on as the body of the beast flipped under them and fell to the ground.

She felt Paul squirming behind her to right himself on the seat. “What was that thing doing?” he asked.

Unfortunately, they got their answer a second later.

With a loud sputter of electronic coughs, then a low whine that sounded like a baby elephant caught in a trap, the Windbike quit working. Completely.

This time, Sofia and Paul screamed in unison as they dropped toward the ground far below.

Tick had halved the distance to Sato and his captors in a matter of seconds. Even though they could fly, the fangen were no match for the Windbikes when it came to speed.

Tick leaned forward, keeping his eyes focused on his target.

He tried not to think of what would happen if they suddenly decided to drop Sato.

Mothball used the Barrier Wand like a staff, swinging it in wide arcs as she darted about on her Windbike, knocking the heads of the fangen, sometimes two or three at a time. She realized they’d be in a whole heap of mess if she broke the ruddy Wand, but Master George had always said the things were sturdy enough to withstand most punishment.

She’d just landed a particularly nice hit on a creature when she caught a flicker of dark movement to her right. She looked to see Paul and Sofia—and their bike—plummeting toward the ground.

She zoomed in that direction without an instant’s hesitation.

Sofia’s Windbike sputtered sporadically, humming to life with a jolt for the briefest of moments before dying again. Paul hugged Sofia tightly from behind, probably hoping she’d never bring it up again should they somehow survive.

But Sofia knew they’d be dead in seconds, and wondered what life as a Realitant might’ve been like. She thought she might have liked it.

Mothball didn’t have time to think or ponder several options. Only one made sense, and she went for it, quickly stuffing the Barrier Wand through a belt loop with one hand while she steered with the other.

In a nosedive that made her eyes water, she rushed toward Sofia and Paul, who clung to their useless Windbike as it plummeted in a downward spiral. Their present course would smash them against a group of boulders clustered close to the river. Mothball intended to change that course.

At the last second before she caught up with the falling bike, Mothball swerved hard to the right then arrowed back in straight at Sofia and Paul, keeping pace with their rate of descent, knowing she only had one shot. As soon as she made contact, Mothball gunned her own Windbike, pushing the other one at an angle as it fell.

Toward the river.

What had been certain death was now a chance.

If the ruddy water was deep enough.

Tick flew up and over the stone parapet bordering the massive crown of the castle, then skimmed along the loose gravel covering the roof. The two fangen had touched down, folding their wings behind them; Sato was clutched between them, his head hanging low.

When they spotted Tick, the two fangen howled out a piercing cry, seeming to dare Tick to attempt a rescue. From both sides of the castle walls, more of the creatures charged in, hungry to join the fight.

Tick never slowed down.

“Sato!” he screamed. “Duck!”

The boy showed no signs he’d heard or even planned to do as he was told, but Tick knew he had no other choice. He leaned forward, trying to envision in his mind what he was about to do.

“Sato!” he screamed again, only thirty feet away. “Duck—NOW!”

To Tick’s relief, Sato buckled his legs and fell toward the roof, catching his captors by surprise. Though they didn’t let go, both fangen looked down at Sato, their attention diverted for an instant, their heads high enough to serve as a perfect target.

Tick yanked back and to the left on the handlebars, leaning hard to the left as the Windbike spun, slowing as the back end swerved around and slammed into the upper bodies of the two fangen. Tick felt a jolt of pain as one of the creatures bit at his right leg before it toppled over. Both of the horrible creatures let go of Sato, stunned by the sudden impact.

Tick steadied the Windbike and lowered it all the way to the loose rocks of the roof. “Get on!” he yelled. Dozens of fangen were charging right for them.

Sato was bruised and battered, his face still pale with the terror of being captured, but he crawled to the bike and pulled himself onto the seat, Tick helping him the last few inches.

Out of the corners of his eyes, Tick saw a blur of yellowed skin and vicious claws. He felt an icy touch on his elbow. Before anything could take hold, Tick shot the Windbike up and away from the sea of disgusting monsters.

A storm of fangen took flight in pursuit.

Paul had absolutely no idea what happened.
