Rachel has been in love with Alistair for 15 years. Even though she’s now married to someone else. Even though she was a teenager when they met. Even though he is 20 years older than her. Rachel and Alistair’s summer love affair on a remote, sun-trapped Greek island has consumed her since she was 17, obliterating everything in its wake. But as Rachel becomes increasingly obsessed with reliving the events of so long ago, she reconnects with the other girls who were similarly drawn to life on the island, where everyone acted in ways they never would at home. And as she does so, dark and deeply suppressed secrets about her first love affair begin to rise to the surface, as well as the truth about her time working for an enigmatic and wealthy man who controlled so much more than she ever could have realized.
