Book 5 of the mesmerizing series The Edge Chronicles. Please read my review here, as my review covers the entire series as a whole:

(For the whole series): I blasted through all of these the first time I read them. Stewart and Riddell created an amazing world, where rocks float and there are a bunch of different humanoid beings running around, each with their own outlook on life and way of living. You can read them in published order or reorganize them into internal chronological order, as some of the characters turn out to be the grandparents of other characters. Either way, a good rollicking read with characters you might actually care about. The pen-and-ink illustrations top it off – interesting, complex, and perfect for the story.
