The iron wheel began to spin slowly at first then faster & faster. The room grew darker. As the light lessened so did the sound. Deeba & Zanna stared at each other in wonder. The noise of the cars & vans & motorbikes outside grew tinny.. . The wheel turned off all the cars & turned off all the lamps. It was turning off London. Zanna & Deeba are two girls leading ordinary lives until they stumble into the world of Un London an urban Wonderland where all the lost & broken things of London end up.. .and some of its lost & broken people too. Here discarded umbrellas stalk with spidery menace carnivorous giraffes roam the streets & a jungle sprawls beyond the door of an ordinary house. Un London is under siege by the sinister Smog & its stink-junkie slaves; it is a city awaiting its hero. Guided by a magic book that cant quite get its facts straight & 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 Un London locals including Brokkenbroll boss of the broken umbrellas Obaday Fing a couturier whose head is an enormous pincushion & an empty milk carton called Curdle. The world of Un London is populated by astonishing frights & delights that will thrill the imagination.
