From the New York Times bestselling author of Never Have I Ever comes a chilling story of sisters and revenge.

Revenge...it's all relative.

Born three minutes apart, Penny and Nix Albright grew up doing everything together, close as only twins can be. But when Nix dies in a tragic accident soon after college, she leaves behind a cryptic voicemail that has Penny guilt-ridden and desperate for justice. 

Five Years Later

Penny has found new purpose as a rookie cop. She’s working to fulfill Nix’s dream of making the world a safer place, but following that dream becomes a nightmare when she’s called to her first murder scene. When she sees the victim, she knows him instantly. It’s Danny Bowery—one of three men she’s long blamed for Nix’s death—splayed in a pool of blood outside a posh Atlanta shopping center, almost as if she’d wished it so.

Stunned, Penny steps away to catch her breath and discovers a blonde in blood-drenched clothes gripping a box cutter. Before Penny can arrest her, the woman reveals that Bowery’s murder is part of a larger story that is far from over. A story about sisters. And with that, the killer disappears.

Now, Penny will stop at nothing to pursue this dangerous woman and learn why she’s avenging Nix’s death. The deeper she dives into the mystery, the less clear it becomes who is hunting whom in this captivating page-turner of hidden motives and deadly consequences.
