“Leo felt trapped. He’d once been stuck in a cave on top of Pikes Peak, surrounded by a pack of werewolves. Another time he’d been stuck in an abandoned factory with a family of evil Cyclopes. But this—standing in an open clearing with a dozen pretty girls—was much worse.”

“Leo could run pretty fast when someone was trying to kill him. Sadly, he’d had a lot of practice.”

“He’d learned years ago it was better not to dwell too much on who was related to whom on the godly side of things. After Tyson the Cyclops adopted him as a brother, Percy decided that that was about as far as he wanted to extend the family.”

“Leo gestured to the empty core. “The syncopator goes here. It’s a multi-access gyro-valve to regulate flow. The dozen glass tubes on the outside? Those are filled with powerful, dangerous stuff. That glowing red one is Lemnos fire from my dad’s forges. This murky stuff here? That’s water from the River Styx. The stuff in the tubes is going to power the ship, right? Like radioactive rods in a nuclear reactor. But the mix ratio has to be controlled, and the timer is already operational.”Leo tapped the digital clock, which now read 65:15. “That means without the syncopator, this stuff is all going to vent into the chamber at the same time, in sixty-five minutes. At that point, we’ll get a very nasty reaction.”Jason and Piper stared at him. Leo wondered if he’d been speaking English. Sometimes when he was agitated he slipped into Spanish, like his mom used to do in her workshop. But he was pretty sure he’d used English.”

“Frank tugged again with no luck. Even Hazel was trying not to laugh.Frank grimaced with concentration. Suddenly, he disappeared. On the deck where he’d been standing, a green iguana crouched next to an empty set of Chinese handcuffs.“Well done, Frank Zhang,” Leo said dryly, doing his impression of Chiron the centaur. “That is exactly how people beat Chinese handcuffs. They turn into iguanas.”

“Oh, no way," Leo said. "We've been sitting in a cave and you get the luxury tent? Somebody give me hypothermia. I want hot chocolate and a parka!”

“He turned to Frank who was trying to pull his fingers out of the Chinese handcuffs…“Okay,” Frank relented. “Sure.” He frowned at his fingers, trying to pull them out of the trap. “Uh, how do you—”Leo chuckled. “Man, you’ve never seen those before? There’s a simple trick to getting out.”Frank tugged again with no luck. Even Hazel was trying not to laugh.Frank grimaced with concentration. Suddenly, he disappeared. On the deck where he’d been standing, a green iguana crouched next to an empty set of Chinese handcuffs.“Well done, Frank Zhang,” Leo said dryly, doing his impression of Chiron the centaur. “That is exactly how people beat Chinese handcuffs.
