Zanna and Deeba, twelve-year old best friends, think that their lives are pretty normal. But when the girls follow a broken umbrella down into the world of Unlondon, a world on the brink of war against the Smog, they learn that their lives are a little more significant than they thought. Zanna is a girl long-prophesized as the Shwazzy – the girl who will save Unlondon (and London) from the Smog. But when an attack leaves Zanna with no memory of having traveled to Unlondon, Deeba remains the abcity’s only hope against the Smog. With her pet milk carton Curdle, a pincushion-headed man, a group of utterlings, a book, and a bus conductor, Deeba sets off to prove to Unlondon’s Propheseers that there is an evil plot afoot. If you liked The Phantom Tollbooth by Norman Juster, or Coraline by Neil Gaiman, this book is perfect for you!
