On a trip to the tropical paradise where her fiancée died, a young woman begins to suspect the death was no accident—and the killer’s still on the island—in this twisty thriller from the New York Times bestselling author of Reese’s Book Club pick We Were Never Here.

Paradise hides a deadly secret.

When Abby steps foot on Isla Colel, she isn’t sure what—if anything—she’ll find. She only knows that she needs to see the place where her fiancée, Eszter, died to try and make sense of the tragic accident.

The island is nothing like Abby expected: Though it was once a bustling tourist hub, a hurricane has left it a shell of its former self, with only a handful of residents remaining. Even the once-daily ferry to the mainland now runs every week or so.

There, Abby befriends an alluring group of expats, but her sense of unease surges when one of them says he knows the truth about Eszter’s final days. Before he can tell her more, though, he vanishes from the island. Hours turn to days with no sign of him, and the others are chillingly cavalier about his disappearance.

As her quest for the truth unearths dark secrets, shady pasts, and a web of lies, Abby grows more determined than ever to find out what happened to the love of her life. And the deeper she gets in the close-knit expat community, the more she suspects that one of them is Eszter’s killer—and will do anything to keep the truth buried. But will Abby discover who it is before she becomes the island’s next victim?
