Wow, when I opened up this book I didn’t expect to fly through it in less than 6 hours. I just could not stop reading. It’s so fast paced and engaging that it’s impossible to put down.

This is a gripping, twisty young adult mystery that you’ll devour in one sitting! The plot is thoroughly intriguing, keeping you hooked from start to finish. Rory Power is a brilliant author, and her previous works, especially Wilder Girls, are also exceptional—ones I highly enjoyed and recommend to any thriller enthusiast!

The story revolves around 17-year-old Nan, who recently lost her three best friends. A year ago, she joined Luce, Edie, and Jane on a night boat tour that ended in Devil’s Eye Canyon. Nan was the only one who returned. No one knows what happened to the other three girls—except Nan. She knows because she killed them.

On the one-year anniversary of the tragedy, the residents of Saltcedar, including the families of the missing girls, gather for a vigil. But during the ceremony, something unexpected happens: Luce returns. Nan suspects the girl claiming to be Luce is an impostor because Nan is certain she killed her, smashing her head with a rock. Luce wasn’t breathing when Nan left her. But now, she’s alive and claims to remember nothing.

Could it be true? How did she survive the head trauma, and where has she been hiding for the past year? Why has she returned now? Is she planning revenge? Meanwhile, someone knows what Nan did. Someone has found the keepsakes Nan secretly took from the dead girls. But who? Nan must act quickly to protect her secret—but what if there are even darker truths waiting to be uncovered?

Overall, the twisty ending was masterfully executed. While I predicted a few elements, I didn’t see the full picture coming. It’s a short, fast-paced, surprising, and well-developed thriller with a fantastic ending. I highly recommend it to anyone seeking something gripping, smart, and quick to read!
