Homicide detective Kate Farrer took a four-month leave from the force when the stress of the job threatened to crush her. Now she's back, at a crime scene as brutal as any she's ever witnessed. The charred corpse of a young woman, burned beyond recognition, smolders on a bed near a bag full of baby items. An autopsy reveals that the victim had recently given birth. Yet no child has been found.

Teaming up with a new partner, Oliver Parke, Kate struggles to hold her own demons at bay—while also pursuing leads in the seemingly unrelated affair of a missing teenager who was keeping secrets that may have cost her her life. But as disturbing clues begin linking their two investigations—and another unspeakably cruel murder secures the knot—Kate and Oliver realize with horror that a desperate killer's next victim might be the most innocent one of all.
