It happened in broad daylight--a pretty fifteen-year-old had saddled up for an afternoon ride and never came back. Left behind was only a splintered fence, the tracks of a pickup truck, a discarded riding boot, and a great deal of blood. As a mother herself, Cincinnati detective Sonora Blair knew she was looking at a parent's worst nightmare. As a homicide cop, she tried not to think about what might be happening to the young girl right now--or what the police would find if they didn't get to her in time. But nothing in Sonora's experience could prepare her for the chilling revelations that would emerge from this case--or for the truth about other missing children, a lover's betrayal, and another unthinkable crime.
