When Patrick is invited by his girlfriend to join her and her family on a luxury holiday in a remote and beautiful part of Scotland, he has no idea that he is about to be plunged into a nightmare of a family, sinister behavior…and a plot to murder the patriarch’s younger fiancée.

Arriving at the house, Patrick meets Holly’s dad, self-made-millionaire Charles, along with her brother Lewis and older sister Miranda. Also on the trip is the widowed Charles’ bride-to-be, Jasmine, who—in her thirties—is around the same age as the three siblings. Lewis and Miranda are horrified by their dad’s impending marriage to this younger woman. Surely, she is just after his money—and is going to steal their inheritance from them. To make things worse, Jasmine is an almost exact doppelganger of their mother before she got sick and died.

Patrick finds himself in the middle of this viper’s nest, trying to keep out of the family crosshairs. He starts to suspect that Lewis has dark plans for Jasmine—putting himself in peril as a potential witness who could mess up his scheme. Perhaps more than one person won’t escape this family of snakes…
