...and some of its lost and broken people too. Here discarded umbrellas stalk with spidery menace, carnivorous giraffes roam the streets, and a jungle sprawls beyond the door of an ordinary house. UnLondon is under siege by the sinister Smog and its stink-junkie slaves; it is a city awaiting its hero. Guided by a magic book that can’t quite get its facts straight, and pursued by Hemi the half-ghost boy, the girls set out to stop the poisonous cloud before it burns everything in its path. They are joined in their quest by a motley band of UnLondon locals, including Brokkenbroll, boss of the broken umbrellas, Obaday Fing, a couturier whose head is an enormous pincushion, and an empty milk carton called Curdle.
