“I’ll get ’em!” yelled Coach Hedge.
He spun the port ballista. Before Annabeth could yell, “Don’t be stupid!” Hedge fired. A flaming spear rocketed toward the chariot.
It exploded over the heads of the pegasi and threw them into a panic. Unfortunately it also singed Frank’s wings and sent him spiraling out of control. Leo slipped from his grasp. The chariot shot toward Fort Sumter, slamming into Jason.
Annabeth watched in horror as Jason—obviously dazed and in pain—lunged for Leo, caught him, then struggled to gain altitude. He only managed to slow their fall. They disappeared behind the ramparts of the fort. Frank tumbled after them. Then the chariot dropped somewhere inside and hit with a bone-shattering CRACK! One broken wheel spun into the air.
“Coach!” Piper screamed.
“What?” Hedge demanded. “That was just a warning shot!”
