The New York Times bestselling author of Elevator Pitch and master of psychological suspense returns with a riveting thriller in which the possible heirs of a dying tech millionaire are mysteriously being eliminated, one by one. Tech millionaire Miles Cookson has more money than he can ever spend, and everything he could dream of-except time. He has recently been diagnosed with a terminal illness, and there is a fifty percent chance that it can be passed on to the next generation. For Miles, this means taking a long hard look at his past… Two decades ago, a young, struggling Miles was a sperm donor. Somewhere out there, he has kids-nine of them. And they might be about to inherit both the good and the bad from him-maybe his fortune, or maybe something much worse. As Miles begins to search for the children he's never known, aspiring film documentarian Chloe Swanson embarks on a quest to find her biological father, armed with the knowledge that twenty-two years ago, her mother used a New York sperm bank to become pregnant. When Miles and Chloe eventually connect, their excitement at finding each other is overshadowed by a series of mysterious and terrifying events. One by one, Miles's other potential heirs are vanishing-every trace of them wiped, like they never existed at all. Who is the vicious killer-another heir methodically erasing rivals? Or is something even more sinister going on? It's a deadly race against time…
