Christina and her cousin Will have run away to London, like a pair of fairy-tale lovers. Will's passionate ambition to design, make and fly aeroplanes is a hard one to realize, and Christina also has battles to win, including coming to terms with the fact that she must always come second to Will's love of aeroplanes. The Edge of the Cloud won the Carnegie Medal and is the second of the Flambards sequence of novels to be reissued in Oxford Children's Modern Classics.
