Eight friends went on a trip. Only six made it out alive. Now a killer has one night to make sure the survivors pay for what they did . . . so that zero make it out alive. From the author of Perfect Little Monsters comes another incredible twisty thriller.

Sadie, Will, Isla, Anthony, Emily, and Charlie are survivors. They were the six (out of eight) to return from a ski holiday turned nightmare two years ago. Although... nobody knows exactly what happened; the details hushed up via the wealth and connections of Sadie's rich parents.

When an exclusive private island with a mansion for rent goes viral on social media, their graduating class persuades Sadie to rent it for the weekend. The six arrive first by helicopter and wait for the rest of their classmates to join them by boat the next day.

But nobody ever comes.

Cut off from the rest of the world with no cell service and no means off the island, paranoia and terror mount as they start to be picked off one by one by an unseen killer. Their past has finally caught up with them, and they'll need to figure out who is killing them before they all wind up dead.
