Eve Renner loved Cole Dennis--until the moment he tried to kill her. That was three months ago, when Eve was lured to a cabin where she found an old friend brutally murdered. Eve is almost positive it was Cole's face she saw right before she was shot. But her memories were too shaky to stand up to trial. Cole is a free man again. And a new string of killings has begun.

The murders all link back to Our Lady of Virtues, the asylum where Eve's father worked as a doctor. She wandered those hallways as a child, exploring hidden rooms and chambers, too young to understand what was happening there. Now, with every victim found, each body tattooed with a number, the pieces of a deadly puzzle fall into place--and all point back to Eve and the ruins of the once-grand hospital.

Detective Reuben Montoya and his partner, Rick Bentz, once convinced of Cole's guilt, now suspect a deeper evil at work. Eve knows she has little choice but to return to Our Lady of Virtues--and to trust Cole in her search for answers. But as Eve's memories gradually return, they only lead her closer to danger, toward the final, meticulously planned act of a killer obsessed with vengeance--and with her.
