Crawl: The Sullivan Gray Series, Book 4 (Unabridged‪)‬

Four years ago, 17-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. 

The Sullivan Gray Series is mystery and suspense with a paranormal twist and the brother dynamic of shows like Supernatural.
