The long-awaited sequel to Shades of Grey gives us further insight in Chromatic society, tradition and politics, as well as into the background of the whole world.
Where the first book gently snowed it’s weirdness on the mountaintops, the second one turns all of it into a landslide – and as with every proper landslide it’s a nice, far away spectacle until it suddenly slams into you.

As with the first book, I cannot recommend this highly enough. And I really want to read more of Fforde’s stuff. And apropos more: third book WHEN?
