Hawthorne College is quieting down for the holidays. But as Riley Stone and her Mu Kappa Epsilon sisters prepare to deck the halls with a series of seasonal parties, a black-masked stalker begins killing sorority women one by one.

It's déjà vu all over again for Tree Gelbman, the snarky sorority sister who solved her own murder by repeatedly reliving her death. When the masked campus killer mysteriously returns to terrorize new targets, Tree cycles through another time loop of clever chills and suspense in the inventive follow-up to Blumhouse's hit thriller.
