Chapter 12 - Chapter 12: River's Secret

Percy kicked through the Mississippi's murky depths, Cynthia's arm hooked firm over his shoulder. The water had caught them soft, but the bank rose steep with jagged roots and silt-slick rocks. He angled hard, muscles burning, until his fingers dug mud."Almost there," he grunted, heaving.Cynthia found footing, scrambling up with a grunt, winged shoes caked brown. She collapsed to knees, dark waves dripping rivers down her olive skin, chest heaving. Obsidian eyes flicked back worried. "Percy—come on.""Yeah," he said, but lied. The current tugged insistent—not rough, but calling. Deep hum vibrated bones. Wait."Hold position," he told her. "One sec."Her brow furrowed—smart suspicion flash—but nodded. "Make it quick."He dove.Dark green silence swallowed, pressure easing like old friend. Current swept downstream gentle, lungs calm, body weightless. Dad?Glow ahead cave; Percy glided in, bubbles ribbon.Algae cavern shimmered blue; naiad coalesced water-form, eyes endless sea. "Son of Poseidon," she trilled melody. "Lord's word."Heart raced. "My father?""Santa Monica pier—Underworld eve. Bolt stolen twice. Hades clear. Gifts betray." Lilt urgent. "Mother endures. Hope sails. True course."Visions danced: Sally alive, mist-cloaked smile? Percy surged forward. "She's okay? Tell me—"Naiad shimmered gone. Current cradled out.Surface breach Cynthia-side; gasp air, scramble bank. She crouched tense, knives half-drawn. "Percy! What the hell—you vanished!""Naiad," he coughed, clutching side wound. "Dad's message. Santa Monica before Underworld—bolt double-theft. Mom's… alive. Hope not lost."Eyes widened, naive hope light smart doubt shadow. "You dove silent? Thought river ate you!""Sorry." Grin sheepish, hand out. "Pulled too strong. Couldn't fight."She huffed exasperated, hauling up. "Idiot. Warn next time. Can't lose you."Reunion MayhemArch base pandemonium: sirens wail, tourists swarm elevator wreckage, police lights strobe. Annabeth/Grover curb-edge frantic—Annabeth ponytail frayed, Grover hooves stamp panic."Percy!" Annabeth barreled, grabbing shoulders. "Elevator plunged—we waited forever—thought you guys…""Echidna," Percy panted. "Chimera as Chihuahua. Elevator death-trap. River break."Grover bleated aghast. "Monster mom? St. Louis?"Cynthia squeezed water shirt. "Barely. Percy water-grabbed me mid-fall."Annabeth eyes narrowed razor. "Start to finish. Now."Percy spilled breathless: floral lady Chihuahua morph, elevator crush-clash swords/knives, Echidna gloat, desperate window-jump. Naiad whisper end."Santa Monica," Annabeth breathed scheming. "Ocean access—smart gate."News van screeched: "Arch terror! Four suspects bus-bomb linked!" Sketches flashed—bus stop, now Arch chaos blurred.Grover whimpered. "National now."Police flood; group shadow-slip woods fast, packs thump heavy. "Denver?" Percy gasped."Tracks," Annabeth affirmed. "Run."Iris DenverTrain rocked foothills, sleeper sway dim. Medusa cash snagged tickets; drachmas rainbow sink-fountain.Mist gleamed Chiron; Luke answered—sweat arena-glisten, gold hair tousled, blue eyes snap. "Percy? Whole team?""Luke!" Annabeth bright relief. "Chiron near?""Drills. News?"Percy leaned close: "Medusa bagged. Echidna/Chimera Arch fight. Naiad: Santa Monica Underworld-before—bolt stolen twice, Hades not thief."Luke brow knit. "Double? Ares scheme? Gods twist."Cynthia edge-hover. "Mom hope—naiad swore alive."Luke grave nod. "Gifts treacherous. Watch. Chiron updated soon. Stay alive."Mist swirl gone; bunks claimed weary. Fugitives infamous, plot thickens, team forged fire. Denver lights streak; west relentless pull.
