Either you're in or you're out.

Welcome to the Thrashers, the elite friend group at New Helvetia High.

They’re everything everyone wants to be.

Jodi Dillon was never meant to be one of them. Julian, Lucy, Paige, and the infamous Zack Thrasher are rich, sophisticated, and love attention. Jodi feels out of place, but Zack’s her childhood best friend, so she’s in.

Then Emily Mills, who desperately wanted to be a Thrasher, dies—and the whispers about the Thrashers begin. As Emily’s journal surfaces, detectives close in, and Jodi faces an impossible choice: betray her friends or protect herself.

But as eerie messages and strange occurrences escalate, it becomes clear—Emily isn’t done with them yet.
