When serial killer Sage Wellington escapes from prison during a medical transfer, FBI Agent Sidney Stone knows exactly how dangerous she is—Sidney is the one who put her away.

But this time, Sage isn’t running. She’s hunting.

Ruthless and brilliant, Sage has a list: lenient judges who failed their victims. Bodies start turning up across Texas, crime scenes staged as robberies. As Sidney and her partner Alex Kane race to decode the pattern, it’s clear Sage is always three steps ahead—rebuilding her identity and executing a vendetta years in the making.

Sidney’s hunt takes her from Maryland to Texas, tracking a killer who thrives on control while she’s losing hers: pregnant, exhausted, and out of time. To stop Sage’s final, most devastating act—a kill designed to shock the entire justice system—Sidney may pay the ultimate price.
