`UnLondon is at war. We're under attack. And it's been written, for centuries, that you - you - will come and save us.'

Stumbling through a secret entrance, Zanna and Deeba emerge in the strange wonderland of UnLondon. Here all the lost and broken things of London end up, and some of its people, too - including Brokkenbroll, boss of the broken umbrellas and Hemi the half-ghost boy. UnLondon is a place where Routemaster buses have legs, where Librarians are `bookaneers', intrepid adventurers dedicated to hunting down lost books, and postmen spend years tracking the mobile addresses of the ever changing Puzzleborough. But the girls have arrived at a dangerous time - UnLondon is under siege by the sinister Smog; it's a city awaiting its hero.

China makes extraordinary use of the ordinary is this wildly inventive fantasy adventure.
