On an island on the coast of Cornwall, cut off from the mainland by the tides for most of the day, 13 old friends meet at Tregowan Castle for a weekend of revelry. By the next evening, only 12 are still alive. Amongst them is a killer—but who? As a storm traps them on the island and past betrayals and grievances are revealed, nerves fray and friendships begin to fracture. But with no escape and no way of calling for help, it’s only a matter of time before the killer strikes again. And when everyone is keeping secrets, anybody could be the next victim.

My husband is a doctor. He’s smart and charming, and everybody trusts him. Except me. On the surface, it looks like I have it all–the perfect marriage, the perfect husband, the perfect life. But it’s far from the truth. Doctor Drew Devlin is not the respectable figure he makes out to be. The reason we moved to this beautiful, old property with a gorgeous view of the sea was because we needed to put our past behind us. It should’ve been a fresh start for us both.

I sit sipping champagne in the warm water, bubbles frothing around me as I admire the breathtaking view of gorgeous blue skies and mountains. I can’t believe I’m here, at this stunning holiday home. It’s to die for....
