“Weaknesses?” Frank asked. “Please tell me they have weaknesses.”
Hazel scowled. “Horses. They hate horses—natural enemies, or something. I wish Arion was here!”
The gryphons shrieked. They swirled around the nest with their red eyes glowing.
“Guys,” Frank said nervously, “I see legion relics in this nest.”
“I know,” Percy said.
“That means other demigods died here, or—”
“Frank, it’ll be okay,” Percy promised.
One of the gryphons dived in. Percy raised his sword, ready to stab the egg. The monster veered off, but the other gryphons were losing their patience. Percy couldn’t keep this standoff going much longer.
He glanced around the fields, desperately trying to formulate a plan. About a quarter mile away, a Hyperborean giant was sitting in the bog, peacefully picking mud from between his toes with a broken tree trunk.
“I’ve got an idea,” Percy said. “Hazel—all the gold in these nests. Do you think you can use it to cause a distraction?”
“I—I guess.”
“Just give us enough time for a head start. When I say go, run for that giant.”
Frank gaped at him. “You want us to run toward a giant?”
“Trust me,” Percy said. “Ready? Go!”
Hazel thrust her hand upward. From a dozen nests across the marsh, golden objects shot into the air—jewelry, weapons, coins, gold nuggets, and most importantly, gryphon eggs. The monsters shrieked and flew after their eggs, frantic to save them.
Percy and his friends ran. Their feet splashed and crunched through the frozen marsh. Percy poured on speed, but he could hear the gryphons closing behind them, and now the monsters were really angry.
The giant hadn’t noticed the commotion yet. He was inspecting his toes for mud, his face sleepy and peaceful, his white whiskers glistening with ice crystals. Around his neck was a necklace of found objects—garbage cans, car doors, moose antlers, camping equipment, even a toilet. Apparently he’d been cleaning up the wilderness.
Percy hated to disturb him, especially since it meant taking shelter under the giant’s thighs, but they didn’t have much choice.
“Under!” he told his friends. “Crawl under!”
They scrambled between the massive blue legs and flattened themselves in the mud, crawling as close as they could to his loincloth. Percy tried to breathe through his mouth, but it wasn’t the most pleasant hiding spot.
“What’s the plan?” Frank hissed. “Get flattened by a blue rump?”
“Lay low,” Percy said. “Only move if you have to.”
The gryphons arrived in a wave of angry beaks, talons, and wings, swarming around the giant, trying to get under his legs.
The giant rumbled in surprise. He shifted. Percy had to roll to avoid getting crushed by his large hairy rear. The Hyperborean grunted, a little more irritated. He swatted at the gryphons, but they squawked in outrage and began pecking at his legs and hands.
“Ruh?” the giant bellowed. “Ruh!”
He took a deep breath and blew out a wave of cold air. Even under the protection of the giant’s legs, Percy could feel the temperature drop. The gryphons’ shrieking stopped abruptly, replaced by the thunk, thunk, thunk of heavy objects hitting the mud.
“Come on,” Percy told his friends. “Carefully.”
They squirmed out from under the giant. All around the marsh, trees were glazed with frost. A huge swath of the bog was covered in fresh snow. Frozen gryphons stuck out of the ground like feathery Popsicle sticks, their wings still spread, beaks open, eyes wide with surprise.
Percy and his friends scrambled away, trying to keep out of the giant’s vision, but the big guy was too busy to notice them. He was trying to figure out how to string a frozen gryphon onto his necklace.
“Percy…” Hazel wiped the ice and mud from her face. “How did you know the giant could do that?”
“I almost got hit by Hyperborean breath once,” he said. “We’d better move. The gryphons won’t stay frozen forever.”
THEY WALKED OVERLAND FOR ABOUT an hour, keeping the train tracks in sight but staying in the cover of the trees as much as possible. Once they heard a helicopter flying in the direction of the train wreck. Twice they heard the screech of gryphons, but they sounded a long way off.
As near as Percy could figure, it was about midnight when the sun finally set. It got cold in the woods. The stars were so thick, Percy was tempted to stop and gawk at them. Then the northern lights cranked up. They reminded Percy of his mom’s gas stovetop back home, when she had the flame on low—waves of ghostly blue flames rippling back and forth.
“That’s amazing,” Frank said.
“Bears,” Hazel pointed. Sure enough, a couple of brown bears were lumbering in the meadow a few hundred feet away, their coats gleaming in the starlight. “They won’t bother us,” Hazel promised. “Just give them a wide berth.”
