Retired Marine Shane Ryan is a ghost hunter whose troubled past haunts him almost as much as the ghosts he encounters in the line of duty. He's the best. And his reward for excellence? The punishment of being in high demand for jobs to eradicate the worst kind of ghosts – the kind that kill.

His latest assignment is an idyllic island setting with sunny skies, crystal blue ocean and a venerable old lighthouse that makes the scenery picture perfect … except for the malevolent, murderous ghosts marring the living portrait. If Amy, the owner, wasn't Marie Lafontaine's cousin, Shane would have steered clear of Squirrel Island and its diabolical dead. But Detective Lafontaine is his do-or-die friend. He'd do anything for her. Even face Dorothy, the undead Evilena who kills anyone invading her unholy domain. Add two shipwrecked couples to the mix and Shane has more trouble than he wants to handle.

Shane's mission is clear: rid the island of Dorothy and her band of undead while keeping his new charges alive. But how could he know that staying alive meant facing the worst evil ever imagined?
