Can you really change your body just by carrying around a coded note? Sure—the advanced technology of a d-mat booth will transport you anywhere instantly, but can it also make you taller, stronger, more beautiful? Clair is pretty sure the offer is too good to be true. But her best friend, Libby, is determined to give it a try, longing for a new, improved version of herself.

What starts as Libby's dream turns into Clair's nightmare when Libby falls foul of a deadly trap. With the help of Jesse, the school freak, and a mysterious—but powerful—stranger called Q, Clair's attempt to protect Libby leads her to an unimagined world of conspiracies and cover-ups. Soon her own life is at risk, and Clair is chased across the world in a desperate race against time.

Action and danger fuel Sean Williams's near-future tale of technology, identity, and the lengths one girl will go to in order to save her best friend.
