Twinmakers by Sean Williams, 490
Creatively written teen sci-fi novel laced in dystopia. People are dying/disappearing when they try to improve their looks. Weird transports that smack of Star Trek whisk people from place to place. Then they change and are no more than a shadow of their former self. With AIs ruling the world, so much can happen. An excellent read, unfortunately no pictures would paste into the blog so you'll just have to search the shelves for a copy.
