Ever since The Night in Question left her with a hideous scar and no memory of what happened, Theo Lane has been hiding. An aspiring filmmaker, she uses a hidden button cam to keep the world at bay. She spends the entire summer in a Manhattan café, secretly documenting random “subjects.”

Once school starts, Theo finds her best friend has morphed into a flirtatious, short-skirt-clad stranger. Everyone ignores the scar. As if that will make it go away. The café remains her lunchtime refuge.

Her most interesting subject is the Lost Boy, a stranger who comes in every day at the same time. When she finally gets up the courage to talk to him she discovers why: the Lost Boy, Andy, is waiting for someone who said she’d meet him there . . . four days ago. Intoxicated by Andy’s love for this mystery girl, Theo agrees to help him find her, and her unhealthy obsession pulls her into a perilous, mind-bending journey. But is it really Andy’s world she’s investigating? Or is it her own?
