Number one New York Times bestselling master of suspense Dean Koontz takes readers on a twisting journey of lost love, impossible second chances, and terrifying promises.

A decade ago, Emily Carlino vanished after her car broke down on a California highway. She was presumed to be one of serial killer Ronny Lee Jessup’s victims whose remains were never found.

Writer David Thorne still hasn’t recovered from losing the love of his life, or from the guilt of not being there to save her. Since then, he’s sought closure any way he can. He even visits regularly with Jessup in prison, desperate for answers about Emily’s final hours so he may finally lay her body to rest. Then David meets Maddison Sutton, beguiling, playful, and keenly aware of all David has lost. But what really takes his breath away is that everything about Maddison, down to her kisses, is just like Emily. As the fantastic becomes credible, David’s obsession grows, Maddison’s mysterious past deepens—and terror escalates.

Is she Emily? Or an irresistible dead ringer? Either way, the ultimate question is the same: What game is she playing? Whatever the risk in finding out, David’s willing to take it for this precious second chance. It’s been ten years since he’s felt this inspired, this hopeful, this much in love…and he’s afraid.

The fate of the world is in the hands of a father and daughter in an epic novel of wonder and terror by Dean Koontz, the #1 New York Times bestselling master of suspense.

Since his wife, Michelle, left seven years ago, Jeffy Coltrane has worked to maintain a normal life for himself and his eleven-year-old daughter, Amity, in Suavidad Beach. It’s a quiet life, until a local eccentric known as Spooky Ed shows up on their doorstep.

Ed entrusts Jeffy with hiding a strange and dangerous object—something he calls “the key to everything”—and tells Jeffy that he must never use the device. But after a visit from a group of ominous men, Jeffy and Amity find themselves accidentally activating the key and discovering an extraordinary truth. The device allows them to jump between parallel planes at once familiar and bizarre, wondrous and terrifying. And Jeffy and Amity can’t help but wonder, could Michelle be just a click away?

Jeffy and Amity aren’t the only ones interested in the device. A man with a dark purpose is in pursuit, determined to use its grand potential for profound evil. Unless Amity and Jeffy can outwit him, the place they call home may never be safe again.
