The Pool House, by Tasmina Perry, is about a woman who gets the offer to spend summer in the Hamptons, taking the place of a dead guest. The summary says: "To Jem Chapman, it's the chance of a lifetime. An invitation to join a group in an exclusive Hamptons house-share, who could say no? But when she discovers what happened last summer, Jem can't help but feel a chill.
A young woman was found drowned in the house's pool. The housemates said Alice was troubled. She'd been drinking. She couldn't swim...
As Jem gets to know her glamorous new housemates, she realises each has something to hide. What really happened last summer? And who would go to any lengths to keep a person quiet?" The Pool House is out in September 2017.
