They couldn't wait to stay here. An idyllic wellness retreat has opened on an island off the coast of Devon, promising rest and relaxation - but the island itself, known locally as Reaper's Rock, has a dark past. Once the playground of a serial killer, it's rumored to be cursed. But now they can't leave. A woman is found dead below the yoga pavilion in what seems to be a tragic fall. But DS Elin Warner soon learns that the victim wasn't a guest - she wasn't meant to be on the island at all. And they would do anything to escape... The longer Elin stays, the more secrets she uncovers. And when someone else drowns in a diving incident, Elin begins to suspect that the old stories about the island are true. Because history seems to be repeating itself - and the guests might not make it home alive...
