“There’s another one!” Frank pointed. “Strike that. Three, four. Okay, we’re in trouble.”
The creatures circled the train like vultures, delighting the tourists. Percy wasn’t delighted. The monsters had glowing red eyes, sharp beaks, and vicious talons.
Percy felt for his pen in his pocket. “Those things look familiar....”
“Seattle,” Hazel said. “The Amazons had one in a cage. They’re—”
Then several things happened at once. The emergency brake screeched, pitching them forward. Tourists screamed and tumbled through the aisles. The monsters swooped down, shattering the glass roof of the car, and the entire train toppled off the rails.
PERCY WENT WEIGHTLESS.
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.
Percy drew Riptide. He sliced the wing off one monster and sent it spiraling into a tree, then sliced through another that burst into dust. But the defeated ones began to re-form immediately.
“What are these things?” he yelled.
“Gryphons!” Hazel said. “We have to get them away from the train!”
Percy saw what she meant. The train cars had fallen over, and their roofs had shattered. Tourists were stumbling around in shock. Percy didn’t see anybody seriously injured, but the gryphons were swooping toward anything that moved. The only thing keeping them away from the mortals was a glowing gray warrior in camouflage—Frank’s pet spartus.
Percy glanced over and noticed Frank’s spear was gone. “Used your last charge?”
“Yeah.” Frank shot another gryphon out of the sky. “I had to help the mortals. The spear just dissolved.”
Percy nodded. Part of him was relieved. He didn’t like the skeleton warrior. Part of him was disappointed, because that was one less weapon they had at their disposal. But he didn’t fault Frank. Frank had done the right thing.
“Let’s move the fight!” Percy said. “Away from the tracks!” They stumbled through the snow, smacking and slicing gryphons that re-formed from dust every time they were killed.
Percy had had no experience with gryphons. He’d always imagined them as huge noble animals, like lions with wings, but these things reminded him more of vicious pack hunters—flying hyenas.
About fifty yards from the tracks, the trees gave way to an open marsh. The ground was so spongy and icy, Percy felt like he was racing across Bubble Wrap. Frank was running out of arrows. Hazel was breathing hard. Percy’s own sword swings were getting slower. He realized they were alive only because the gryphons weren’t trying to kill them. The gryphons wanted to pick them up and carry them off somewhere.
Maybe to their nests, Percy thought.
Then he tripped over something in the tall grass—a circle of scrap metal about the size of a tractor tire. It was a massive bird’s nest—a gryphon’s nest—the bottom littered with old pieces of jewelry, an Imperial gold dagger, a dented centurion’s badge, and two pumpkin-sized eggs that looked like real gold.
Percy jumped into the nest. He pressed his sword tip against one of the eggs. “Back off, or I break it!”
The gryphons squawked angrily. They buzzed around the nest and snapped their beaks, but they didn’t attack. Hazel and Frank stood back to back with Percy, their weapons ready.
“Gryphons collect gold,” Hazel said. “They’re crazy for it. Look—more nests over there.”
Frank nocked his last arrow. “So if these are their nests, where were they trying to take Percy? That thing was flying away with him.”
Percy’s arms still throbbed where the gryphon had grabbed him. “Alcyoneus,” he guessed. “Maybe they’re working for him. Are these things smart enough to take orders?”
“I don’t know,” Hazel said. “I never fought them when I lived here. I just read about them at camp.”
