The Retreat: Signed Edition

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 . . .
