Robinson Is Back With Another Mindbender. In this book, The Modern Day Master of Science Fiction creates yet another absolute breakneck thriller that also happens to be one of the most mind-bending books of his career, right up there with ALTER and INFINITE. It *also* is one of the few books at this "more developed" stage of his career where he openly wrestles with religious and philosophical issues, and indeed the very debate between our two primary characters on these topics is some of the most intense and intriguing bits of the book. Still, for those who want to gloss over the philosophy and focus on the action, there is still quite a bit of that here as well, and indeed the debates often happen in the middle of the intense action. (Think: Brian and Dom having a debate about the nature of reality *while in the middle of the airplane chase scene* at the end of Fast 6.) There are numerous reasons I call Robinson "The Modern Day Master of Science Fiction", and this book just adds to them. Very much recommended.
