Six friends are trapped. One of them is dead.

One of them is the killer.

Set on a remote storm-swept island called Inishmore off the Irish coast in the Atlantic Ocean, six friends – all originally from the island, but all gone their separate ways – reunite before New Year's Eve.

​

​But the day before New Year's Eve one of the friends is found dead at the bottom of a cliff. Murdered. As a storm descends and they are cut off from the mainland, Cara – who is also the only serving member of the Irish police force on the island – has no choice but to investigate the death of her own friend herself before the storm lifts and the killer can escape from the island.

​

It isn't just a novel about a murder, and a group of close, lifelong friends infested with secrets and lies, rotting them from the inside out. It's a novel about being an outsider, about loneliness and loss, about tradition and superstition, and how greed and guilt can eat you up.
