Un Lun Dun

Strange things are happening to Zanna. Animals are treating her with a weird sort of respect, a woman on the street calls her the "Shwazzy" and her father, in a strange sort of trance, hits her friend with his car. Zanna gets a card in the mail that has "Zanna Moon Shwazzy" written on it. She moves in with her best friend Deeba, because her father needs some time off after the incident. The girls at school avoid her because they're scared. But apart from that, every thing is sort of normal. Until one night, Deeba and Zanna follow a broken umbrella into a basement and find a wheel. Zanna turns the wheel, feeling like for some reason she has to. Deeba and Zanna run out of the basement and find themselves somewhere completely different. It doesn't really calm them down when they notice that there are weird symbols in their cell phones and a trash heap starts attacking them. When they meet Obaday Fing, who sews "haute couture" out of book pages, he explains that they're in an Abcity, UnLondon, and helps them get to the Pons Absconditus where the Propheseers work. The Propheseers know all about Zanna's destiny to combat the Smog that threatens to kill all of the inhabitants of UnLondon. But when some Stink-Junkies (who are contolled by the Smog) come, Zanna is powerless and is forced to go back to London, having lost all memory of UnLondon. For a while everything goes back to normal, until Deeba finds out that many of the Propheseers' allies are in league with the Smog and goes back. But how can a twelve year old girl, a half ghost and a talking book that contains wrong prophecies save the whole Abcity?
