Four years ago, seventeen-year-old spelunker Carter was killed in a cave collapse. The coroner deemed it an accident.
Sullivan Gray knows better.
A camping weekend with his brother Dez takes an unsettling turn when Sully sees Carter’s shattered spirit, a sighting that reveals the teen’s death was, in fact, murder.
The brothers launch an investigation—a job complicated by a marital infidelity case Dez has been handed and the fact Sully remains little more than a ghost himself.
Having once escaped his own death inside a collapsed cavern, Sully knows the dangers lying beneath the earth’s surface. And those dangers only increase when it turns out those at the heart of the mystery—including Carter himself—will stop at nothing to keep their secrets buried.
