The Nameless One, Book 1 of the Cade Saga is the first book in a brand new series of Edge Chronicles by Chris Riddell and Paul Stewart.

We've heard a lot from Chris who creates all the drawings, now Paul Stewart tells us a bit more about the books: "There are wars, refugees, religious fanatics and petty dictators in the Edge, and a harsh landscape that makes survival a constant challenge. But, although it is fantasy, there is no magic. Instead, the natural laws of our world are broken – rocks grow and become buoyant, lightning solidifies and is harnessed for its power, waifs are telepaths, trees can eat you… The first book was published in 1998. Now, in 2014, there are 11 titles in print, with the first of the latest trilogy: The Nameless One: Book 1 of the Cade Sage – just published. Enjoy!"
