Query: Very, very good

This book was as good as any other sci-fi, fantasy, or cyberpunk book currently on the market, such as "Childhood's End", "Foundation", "Ringworld", "Eragon", "Prey", "Neuromancer","Virtual Light", "Altered Carbon", "Darkeye: Cyber Hunter", and so forth. I highly recommend it, just as I would any of these other books or anything remotely related to sci-fi, fantasy, and cyberpunk.
