Last year, Nan’s three best friends ventured into the canyons near their small town and never returned. Now, one of them is back, and Nan can’t believe it…because she’s the one who killed them. From the New York Times bestselling author of Wilder Girls comes another dark thriller about friendship, jealousy, desire, and revenge, with a twist ending that needs to be talked about.

Nan's story has always been the same. Last summer, she, Luce, Edie and Jane took a boat out for one final swim in the river. It was a perfect summer night.

But the only one who returned that night was Nan. She maintains that she has no idea what happened to her three friends. The girls went ahead, and it was as though they disappeared into thin air.

Now, one year later, it's the memorial of that night. All of Saltcedar has gathered at the river. Nan is even wearing the same clothes she wore that fateful day last summer. And when Luce climbs out of the water, no one is more surprised than Nan.

Because Nan killed her. Right before she killed Edie and Jane.
