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 Southern California. 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.
