This inventive fantasy from bestseller Fforde (The Eyre Affair) imagines a screwball future in which social castes and protocols are rigidly defined by acuteness of personal color perception. Centuries after the cryptically cataclysmic Something That Happened, a Colortocracy, founded on the inflexible absolutes of the chromatic scale, rules the world. Amiable Eddie Russett, a young Red, is looking forward to marrying a notch up on the palette and settling down to a complacent bourgeois life. But after meeting Jane G-23, a rebellious working-class Grey, and a discredited, invisible historian known as the Apocryphal man, Eddie finds himself questioning the hitherto sacred foundations of the status quo. En route to finding out what turned things topsy-turvy, Eddie navigates a vividly imagined landscape whose every facet is steeped in the author's remarkably detailed color scheme. Sometimes, though, it's hard to see the story for the chromotechnics.
