Then one day in Central Park, Rose sees something extraordinary: a crystal staircase rises out of the lake, and two small figures climb the shimmering steps before vanishing like a mirage. Only it's not a mirage. Rose is being watched - recruited - by representatives of U Nork, a hidden city where Dirigibles and Zeppelins skirt dazzling skyscrapers that would dwarf the Chrysler building. Impeccably dressed U Norkers glide along the sidewalks on roller skates. Rose can hardly take it all in. Then she learns the most astonishing thing about U Nork. Its citizens are in danger, and they need Rose's help, and hers aloneFrom the Hardcover edition.
