September is a twelve-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 (mightn't you?).

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. Having read enough books to know what a girl with a quest must do, September sets out to Fix Things.

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, losing her shadow, her shoes and her way. But she finds adventure, courage, a rather special Spoon, and a lot more besides . . .
