In the trauma center of Atlanta’s busiest hospital, Sara Linton treats the city’s poor, wounded, and unlucky—and finds refuge from the tragedy that rocked her life in rural Grant County. But when a tortured young woman becomes a patient in her ER, Sara finds herself thrust into a desperate police investigation, coming face-to-face with Special Agent Will Trent and his partner, Faith Mitchell.

In this suspense masterpiece, Karin Slaughter weaves together the moving, powerful human stories of three unforgettable characters from her New York Times bestselling novels Faithless and Fractured, who collide for the first time in an electrifying race against the clock—and a duel with unspeakable human evil. For Sara, Will, and Faith—each with their own wounds and their own secrets—are all that stand between a madman and his next victim.
