Query: Quite possibly the worst sci-fi novel I've ever read

Where to start... this book was so bad on so many levels. Dialog? Idiotic. Characters? At points they almost reached one-dimensional. Premise? Other than some mildly interesting references to quantum physics the rest of the book reads like sixth grade fan fiction. I don't mind the occasional unoriginal story and characters, but this book managed to distill every adolescence fantasy, bad sci-fi cliche, and crap plot device into pure and utter garbage. Amazing really.
