Gideon’s determined to protect his lover. But after a serious injury on duty, Gideon finds out the hard way that he needs protection too. His job’s on the line and he’s scared. Worst of all, he thinks he knows who that voice belongs to – and he can’t stop Lee from heading off to confront this most terrifying ghost from his past.

When the full spring moon rises over Cornwall’s rugged coast, and the veil between the worlds grows thin, Tyack and Frayne must join forces to solve a decades-old mystery that still has the power to tear their world apart.
