Cabin Eleven smelled of armpits and unwashed canvas, which Jessie could have forgiven if not for the wardrobe doors.
There were four freestanding armoires lining the east wall, warped by salt air, their brass latches stripped long before she arrived. Every night, the hinges drifted open by two inches. Every night, Jessie swung her legs out of her sleeping bag, walked across the cold pine planks, and wedged folded index cards into the jambs until the wood clicked shut. If a door hung open in the dark, her ribs tightened before her lungs did. It was an old reflex from four different group homes with four different locks that didn’t work, and she had no intention of explaining it to twenty-two children of Hermes who already thought her glasses made her look like a substitute teacher.
She tapped the card into the third wardrobe with the heel of her hand. Solid. No give.
Behind her, Travis Stoll snored into a fleece blanket printed with stolen airline logos.
Outside, the bronze sundial in the courtyard caught the early dawn, throwing long, needle-sharp shadows toward the strawberry fields. Jessie touched the mole just under the right corner of her lip—a thumb-check she did whenever she was about to do something stupid—and shoved her hands into the pockets of her faded denim jacket. Her inhaler was in the left; two spare canisters of albuterol were zipped into her duffel. She had three weeks of medicine left, assuming she didn't get chased by anything with leather wings.
Chiron had told her the mist would thin by midsummer, which was a polite way of saying her lungs were on borrowed time.
She skipped the pavilion breakfast. The smell of burning sausages offered to the sky made her throat itch, therefore she took the gravel track down toward the canoe lake, where the mist still sat heavy on the reeds. She wasn't looking for scenery. Two days ago, during chariot maintenance, she’d noticed the wheelwright shed behind the armory had a padlocked sub-floor hatch half-buried under spare bronze rims and rotting leather harnesses. Nobody had cleared that corner since the Battle of Manhattan.
The lock on the hatch wasn’t celestial bronze. It was a standard four-pin Master Lock, rusted orange at the shackle.
Jessie knelt in the dry straw behind the forge racks, pulled a flattened bobby pin and the tension wrench she’d filed down from a butter knife out of her sock, and went to work. Her knuckles scraped the wood. The cylinder resisted, then gave with a dull, wet *snap*.
"You're not supposed to be back here," a voice said.
Jessie didn't jump, though her chest spiked. She kept her knees planted, carefully easing the wrench back into her palm before turning around.
Annabeth Chase stood framed in the shed doorway, gray eyes gray as a wet slate blackboard, a blueprint rolled under one arm and a celestial bronze dagger sheathed at her belt. Her blonde hair was pulled into a high, severe ponytail that left no loose strands. She looked Jessie up and down—stopping for half a second at the pick in Jessie’s fingers, then at the crooked angle of Jessie's glasses.
"Neither are you," Jessie said, standing up. At five-foot-eight, she had an inch on Annabeth, but Annabeth carried her weight like someone used to deflecting charging boars. "Unless the council of counselors holds its meetings between the axle grease and the horseshoe nails."
Annabeth’s jaw tightened. "Chiron asked for an inventory of the southern foundations. The lake run-off is undermining the pilings."
"Right. That's why you're carrying the blueprints for the Athena Parthenos pedestal instead of the camp plumbing." Jessie pointed with her chin toward the ink-stained margin sticking out from the girl's elbow. "I can read backwards, Chase. You've been staring at the limestone specs since yesterday."
Annabeth didn't blush. Her expression shut down, smooth and unreadable as marble. "Cabin Eleven has kitchen duty in twenty minutes, La. If Mr. D catches you wandering, he’ll make your tongue taste like stale grape juice until Tuesday."
"He tries that, he can pay for my pulmonary specialist," Jessie muttered. She didn't move away from the trapdoor. "What's down there?"
"Old campaign gear. Tents. Stretcher frames." Annabeth’s voice was too level, the cadence clipped with the rehearsed ease of someone who had practiced the answer. "Chiron had it sealed in August. It’s unsafe."
"The padlock was hardware-store steel," Jessie said. "Bought within the last six months. The barcode sticker is still half-stuck to the underside of the casing."
Annabeth shifted her weight. Her hand didn't drop to her hilt—she was too smart for that kind of tell—but her fingers curled slightly against the linen of her camp shirt. She was calculating. Jessie knew that look; she’d seen it on caseworkers right before they decided which foster file to bury at the bottom of the drawer.
"Drop the door, Jessie," Annabeth said quietly. "Go get breakfast."
"Give me a reason that isn't a lie."
"You haven't been claimed." The words were cold, delivered without malice, which made them hit harder. "You don't know whose side your blood is on yet. Until you do, you stay out of the camp’s lower levels. That’s Chiron’s rule, not mine."
"Chiron didn't put a Yale lock on a floorboard to keep unclaimed kids from finding old blankets," Jessie countered.
She didn't wait for Annabeth’s permission. Before the older girl could close the distance between them, Jessie hooked her boot heel into the iron ring of the trapdoor and hauled upward. The wood groaned, spitting splinters, but the rusted hinges tore free from the pine floor with a screech that scattered the sparrows in the eaves.
Annabeth lunged forward, hand outstretched to slam it down, but the draft from the hole hit them both first.
It wasn't damp. It didn't smell like earth, or grease, or stagnant lake water.
It smelled like sea brine and scorched tin, dry and hot as an electrical fire.
Jessie dropped to a crouch, reaching blindly into the narrow gap beneath the floor joists before Annabeth could shove her back. Her fingers brushed gravel, then cold cloth, then closed around the rim of an unglazed ceramic jar no larger than a coffee mug. It was wrapped in oilcloth, bound with three strands of thick copper wire that had been twisted shut using pliers.
"Don't touch the wire," Annabeth snapped, her voice losing its icy composure, replaced by something sharp and alarmed. She didn't grab the jar; she pulled her hands back entirely, stepping half a pace into the light.
"What is it?" Jessie demanded. She pulled the jar into her lap. The clay beneath the cloth was vibrating, a faint, rhythmic pulse against her palms like a bird trapped inside an egg.
"Put it back," Annabeth said. Her gray eyes weren't looking at Jessie's face anymore; they were fixed on the copper ties. "Chiron told the senior council the cache was destroyed when the Titan army breached the perimeter. He swore it was burned in the woods."
"He lied to you?" Jessie asked, her tone dry, though her own heart was thudding against her ribs.
"He protected us," Annabeth said, but her voice had a hollow, brittle edge. She wouldn't look at the hatch. She wouldn't touch the jar. "You don't understand what was being traded back then. Luke wasn't the only one who made promises to the other side."
Jessie adjusted her glasses with the knuckle of her thumb, looking down at the wire. Scratched into the wax sealing the neck of the jar was a tiny, crude mark: not an Olympian trident or a caduceus, but a stylized set of scales with the crossbar deliberately snapped in half.
The low hum against her fingers didn't feel divine. It felt heavy, industrial, and distinctly modern—like the vibration of an idling engine buried five miles beneath the grass.
Jessie looked up at the girl who was supposed to have all the answers. Annabeth was staring at the broken seal with the dawning realization of someone who had memorized the entire map, only to find the coastline had never existed.
