September is a 12-year-old girl, somewhat grown and somewhat heartless, and she longs for adventure. So when a green wind and a leopard of little breezes invite her to Fairyland – well, of course, she accepts. When she gets there, she finds a land crushed by the iron rule of a villainous marquess – she soon discovers that she alone holds the key to restoring order. As September forges her way through Fairyland, with a book-loving dragon and a boy named Saturday by her side, she makes many friends and mistakes. But while she loses her shadow, her shoe and her way, she finds adventure, courage, a rather special spoon, and a lot more besides.
