#1 New York Times bestselling author Kathy Reichs steps beyond her classic Temperance Brennan series in a new standalone thriller—featuring a smart, tough, talented heroine whose thirst for justice stems from her own dark past.

Meet Sunday Night, a woman with physical and psychological scars, and a killer instinct….

Sunnie has spent years running from her past, burying secrets and building a life in which she needs no one and feels nothing.

But a girl has gone missing, lost in the chaos of a bomb explosion, and the family needs Sunnie's help.

Is the girl dead? Did someone take her? If she is out there, why doesn't she want to be found?

It's time for Sunnie to face her own demons—because they just might lead her to the truth about what really happened all those years ago.
