This book caught my eye a while ago, and I'd been dying to read it since it seemed like such a novel concept. Sawyer's treatment of the subject is average, though, with little excitement and a simplistic plotline. Not to mention an unnecessary love story. It's a very easy read, despite the detailed discussions of religion, morality and quantum physics that pepper it. Perhaps because these are mercifully cut short just shy of becoming wearying.If you are looking for an exciting sci-fi thriller with an intelligent *story*, not just an interesting concept, this isn't it. Nothing really "goes wrong". For a casual read when you have nothing better to do, it's all right. Think of it as a 12-year-old's science fiction book.
