Luca Laine Thomas lives on a cursed island. To the outside world, Parris is an exclusive, idyllic escape accessible only to the one percent. There's nothing idyllic about its history, though, scattered with the unsolved deaths of young women--deaths Parris society happily ignores to maintain its polished veneer. But Luca can't ignore them. Not when the curse that took them killed her best friend, Polly, three years ago. Not when she feels the curse lingering nearby, ready to take her next.

When Luca comes home to police cars outside her house, she knows the curse has visited once again. Except this time, it came for Whitney, her sister. Luca decides to take the investigation of Whitney's death into her own hands. But as a shocking betrayal rocks Luca's world, the identity of Whitney's killer isn't the only truth Luca seeks. And by the time she finds what she's looking for, Luca will come face to face with the curse she's been running from her whole life.
