Edgar Award-winner Harlan Coben brings us his most astonishing — and deeply personal — novel yet. And it all begins when Myron Bolitar's ex tells him he's a father ... of a dying thirteen-year-old boy.
Myron never saw it coming. A surprise visit from an ex-girlfriend is unsettling enough. But Emily Downing's news brings him to his knees. Her son Jeremy is dying and needs a bone-marrow transplant — from a donor who has vanished without a trace. Then comes the real shocker: The boy is Myron's son, conceived the night before her wedding to another man.
Staggered by the news, Myron plunges into a search for the missing donor. But finding him means cracking open a dark mystery that involves a broken family, a brutal kidnapping spree, and the FBI. Somewhere in the sordid mess is the donor who disappeared. And as doubts emerge about Jeremy's true paternity, a child vanishes, igniting a chain reaction of heartbreaking truth and chilling revelation.

Harlan Coben is the bestselling author of fourteen previous novels, including The Woods, Promise Me, and The Innocent, and is the winner of the Edgar, Shamus, and Anthony awards. He lives in New Jersey with his family.
