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.

Penny and Nicki, Nix and Pen,

Where does one stop and the other begin?

Sisters Penny and Nicki lived life the only way twins can: together. But when Nix dies tragically, she leaves behind a cryptic voicemail that has Penny guilt-ridden and desperate for justice.

Five Years Later

Penny is working her first murder scene as a rookie cop, trying to fulfill her sister's dream to make the world a safer place. But pursuing that dream becomes a nightmare when she realizes that she knows the victim. Danny Bowery—one of three men she's long-blamed for Nix's death—is splayed in a pool of blood outside the Atlanta shopping center.

Stunned, Penny steps away from the scene to catch her breath, and finds a blonde woman drenched in blood and gripping a box cutter. Before Penny can begin to understand what and who she’s discovered, the woman tells her that what happened is part of a story about one thing. Sisters. And the murderess disappears.

Now, Penny will stop at nothing to uncover the truth about who this woman is, why she killed Danny Bowery, and how it connects to Nix’s story…no matter the cost.

Missing Sister is a captivating thriller of hidden motives and deadly consequences.
