Eight strangers. One island. A secret you'd kill to keep. When eight people arrive on the beautiful but remote Buidseach Island, they are ready for the challenge of a lifetime: to live alone for one year. Eighteen months later, a woman is found in an isolated fishing village. She’s desperate to explain what happened to her: how the group fractured and friends became enemies; how they did what they must to survive until the boat came to collect them; how things turned deadly when the boat didn’t come…But first Maddy must come to terms with the devastating secret that left them stranded, and her own role in the events that saw eight arrive and only three leave.
