JAMES PATTERSON WRITES HIS THRILLERS AS IF HE WERE BUILDING ROLLER COASTERS. He grounds the stories with a bare-bones plot, then builds them over the top and tries to throw readers for a loop a few times along the way.

Kristin Burns has lived her life by the philosophy "Don't think, just shoot"-pictures, that is. Struggling to make ends meet, she works full time as the nanny for the wealthy Turnbull family, waiting for her glamorous life as a New York photographer to begin. When her photographs are considered by an elite Manhattan art gallery, it seems she might finally get her career started.

But Kristin has a major distraction: forbidden love. The man of her dreams is almost hers for keeps. Breathless with an inexhaustible passion and the excitement of being within reach of her goals,Kristin ignores all signs of catastrophe brewing.

Fear exists for a reason. And Kristin can only dismiss the warnings for so long. Searching desperately for the truth through the lens of her camera, she can only hope that it's not too late.

With this stunning novel of psychological suspense, James Patterson, "one of the bestselling writers in history" (New York Sun), delivers the most haunting thriller of his career.
