The Morada Survey

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.
