In his seventh Myron Bolitar thriller, Edgar Award winner Harlan Coben brings us his most astonishingâ€”and deeply personalâ€”novel yet. And it all begins when Myronâ€™s ex tells him heâ€™s a father . . . of a dying thirteen-year-old boy. A surprise visit from an ex-girlfriend is unsettling enough. But Emily Downingâ€™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 Myronâ€™s son, conceived the night before Emilyâ€™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 Jeremyâ€™s true paternity, a child vanishes, igniting a chain reaction of heartbreaking truth and chilling revelation.
