Last One Out by Steph Nelson

This chilling thriller unravels the dark secrets behind Chloe Webster’s disappearance and her shocking return twenty-five years later, as her cousin Frankie races to uncover a truth more terrifying than she could imagine.

Chloe Webster is supposed to be dead.

She vanished twenty five years ago—the night her two friends were brutally murdered at an isolated hot springs. At least, that’s what everyone believes.

Everyone except her cousin, Frankie, who never lost hope that Chloe was alive.

When Chloe unexpectedly shows up at her own annual memorial event, Frankie is overjoyed. But this isn’t the reunion she imagined. Chloe has no memory of that night in 1999—or her life before.

Then Frankie starts getting cryptic messages that imply Chloe knows more than she’s letting on. Frankie wants to trust her cousin, but even more, she wants answers to the questions that have plagued her for decades.

But is the truth really worth uncovering at any cost?
