“Fast-paced . . . layered with both tenderness and fun . . . Coben [is] a gifted storyteller.”—The Denver Post

In his seventh Myron Bolitar thriller, Edgar Award winner Harlan Coben brings us his most astonishing—and deeply personal—novel yet. And it all begins when Myron’s ex tells him he’s a father . . . of a dying thirteen-year-old boy.

“A terrific novel . . . Coben’s professionalism is clear from every paragraph in the book.”—The Boston Globe

A surprise visit from an ex-girlfriend is unsettling enough. But Emily Downing’s news brings Myron 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: Jeremy is Myron’s son, conceived the night before Emily’s wedding to another man. Myron is determined to help him. But finding the missing donor means cracking open a dark mystery that involves a broken family, a brutal kidnapping spree, and the FBI. And as doubts emerge about Jeremy’s true paternity, a child vanishes, igniting a chain reaction of heartbreaking truth and chilling revelation.
