Chapter 76 - The Black Tide Rising

Nine millimeter rounds struck her at point-blank range, driving her back step by step until her spine shattered against the trunk of an ancient hemlock. The black ichor geysered from her skull, splattering the bark, and her body finally collapsed into a motionless, tangled heap of limbs in the ferns.
The forest fell into an unnatural, suffocating silence.
Miller was coughing violently on the shoulder of the road, dragging himself up by the cruiser's bumper, his neck marked with deep, purplish-black bruising where her fingers had dug into his flesh. "She... she was dead before she even hit the ground," he gasped, spitting out dark phlegm. "That thing was being puppeteered."
"We don't have time," I said, my hands shaking so violently I dropped the empty slide-locked pistol into the mud. I clutched Leo to my chest. His crying had stopped the instant Chloe fell, returning to that unsettling, rhythmic trance. "They’re using the groundwater. The whole coastal aquifer is infected. Look."
From beneath the fallen body of my sister, the black fluid wasn't soaking into the soil. It was flowing uphill, streaming in thin, thread-like rivulets toward the ditch, seeking the standing water. And from the distant south, beyond the tree line, a deep, continuous rumble began to shake the earth—a sound like a freight train barreling through a tunnel.
It was the roar of the sea breaching the coastal seawalls.
"The Cape Elizabeth lighthouse," Miller muttered, pointing a trembling hand toward the sky.
Above the tree canopy, the sweeping beam of the historic lighthouse had changed. It was no longer the clean, sweeping white beacon that had guided sailors for two centuries. It was pulsing with an angry, corrosive violet light, sweeping in rapid, frantic circles across the storm clouds—a signal flare for the leviathan rising from the trench.
"We have to abandon the car," Miller said, wiping rain and blood from his eyes. "The road ahead passes through the marsh. If the seawall has collapsed, Route 77 is under ten feet of ocean water by now."
"Where do we go?" I asked, looking down at Leo. His small hand had reached out from the blanket, his tiny fingers curling around the silver locket hanging around my neck—the locket my father had given me before his suspicious 'accidental' drowning ten years ago.
Miller looked at the locket, his eyes narrowing in sudden recognition. "Your father’s old surveying cabin. Sovereign Rock."
"Sovereign Rock is on the granite bluffs," I said, a flicker of memory returning. "He said it was built on solid bedrock, above the highest storm surge recorded in state history."
"He didn't just build it for storms, Clara," Miller said, limping toward the tree line and retrieving a heavy waterproof survival pack from the cruiser’s trunk. "Your father was the chief hydrologist for the St. Jude's foundation before he realized what Eleanor was manufacturing. He built Sovereign Rock on a subterranean dome of non-porous pink granite. It’s completely cut off from the coastal aquifer. No pipes, no municipal water, no groundwater seepage. It’s the only place within fifty miles that she can’t reach through the water."

"Then we walk," I said, pulling the wool blanket over Leo’s face to shield him from the driving sleet.
We plunged into the black timber, leaving the road, the dead cruiser, and the twitching remnants of my sister behind us. But as we stepped into the deep woods, the wind carried a sound that made my blood run colder than the Atlantic: the sound of a woman’s laughter, high, elegant, and chillingly familiar, echoing not from the sky, but from every single drop of rain that struck my face.
