A 15-year-old boy wakes to find himself locked in a white cube-shaped room. No windows. No doors. Total silence. He has no memories. No clue how he got there. No idea who he is.

A computer-generated voice named Alice responds to his questions. Through her, he is able to access the internet. As the boy uncovers snippets of his story—an attempted abduction, a critical injury, a murder—it becomes clearer. But when some of the pieces don’t fit, how can he tell what’s real and what’s not? Who can he trust? And who is he really?
