Tiago Varas is a night-shift transit driver who knows every crumbling backroad and dry ravine. He also has a failing heart. When a routine delivery traps him inside the Morada Site—a massive, decommissioned processing facility deep in the arid scrublands—he finds a survey team cut off from the outside world. The facility isn't empty. Something in the deep levels is waking up, and it hunts by listening to the electrical rhythm of human hearts. But Tiago’s arrhythmic, dying heart makes him a ghost to the entities, and his obscure bloodline is the only biological key that can navigate the lower doors. With a structural surveyor, a local scavenger, and an exhausted field medic, Tiago must rely on his unique vulnerability to lead the survivors through the dark, before his chest finally gives out.

When independent demolition specialist Kalliades takes a contract to scuttle the massive, deep-water salvage rig Kymatothia, it seems like a standard hazard job. The rig is isolated above a treacherous sub-surface trench, and the company wants the deteriorating structure gone. But Kalliades bears an ancient oceanic mark on his skin—a trait that makes him uniquely capable of surviving the crushing depths, and precisely what the anomaly beneath the rig is hunting. After a catastrophic structural failure, Kalliades wakes up three days in the past. Now trapped in a repeating time loop, he must use his structural expertise and precise application of explosives to reverse-engineer the disaster, navigate a paranoid crew, and outwit whatever is systematically dismantling the rig from the abyss.
