Where Alison Kerby’s ex-husband goes, trouble follows. This time, unfortunately, he’s brought that trouble right to her doorstep.

For all his faults, Steven is still the father of Alison’s daughter, so with the help of ghosts Maxie and Paul, Alison sets out to find her ex and clear him of the murder. But if the bad guys get to him first, he may not have a ghost of a chance...
