Query: A stylish fantasy that rings true

This stylish fantasy has an intriguing premise: what if there were a world without color? But it takes more than a great idea to make a great novel; it takes fully-realized characters, rich imagery, a world with depth to explore, and, most of all, insight into what we as humans are and what we can be. LORDS OF RAINBOW fulfills its promises and is, quite simply, a great read.
