For Jenny Hislop, her wedding in her coastal hometown in Ireland is meant to be the happiest day of her life. Despite the painful memories the town holds of the parents she’s lost, Jenny’s blissfully happy as she makes her way from the ceremony to the secluded lighthouse for the reception.

Then she finds a dead body on the cliffs. A murder victim. Who looks identical to her husband.

As far as Jenny knows, her husband – still alive and well – is an only child. So, who is this stranger who looks so much like him? Was he killed because of their resemblance? Could he be dead because of a mistaken identity? If so, which of her wedding guests would want her husband dead, and why?

When more wedding guests start to die, two things become crystal clear. One, the people closest to Jenny are hiding deadly secrets from her. And two, this will certainly be a wedding no one will ever forget . . .
