His vision blurred. Claws grabbed his arms and lifted him into the air. Below, train wheels squealed and metal crashed. Glass shattered. Passengers screamed.
When his eyesight cleared, he saw the beast that was carrying him aloft. It had the body of a panther—sleek, black, and feline—with the wings and head of an eagle. Its eyes glowed blood-red.
Percy squirmed. The monster’s front talons were wrapped around his arms like steel bands. He couldn’t free himself or reach his sword. He rose higher and higher in the cold wind. Percy had no idea where the monster was taking him, but he was pretty sure he wouldn’t like it when he got there. He yelled—mostly out of frustration. Then something whistled by his ear. An arrow sprouted from the monster’s neck. The creature shrieked and let go.
Percy fell, crashing through tree branches until he slammed into a snowbank. He groaned, looking up at a massive pine tree he’d just shredded.
He managed to stand. Nothing seemed broken. Frank stood to his left, shooting down the creatures as fast as he could. Hazel was at his back, swinging her sword at any monster that came close, but there were too many swarming around them—at least a dozen.
