The Edge of the Cloud (Oxford Children’s Modern Classics Book 2)

Christina and Will have escaped Flambards for London with their heads full of dreams, only to find a whole new set of problems. Not only the basic ones of work and a place to live, but Will's single-minded ambition to design and pilot flying machines, which terrifies Christina every time he leaves the ground. Will is certain he can become a success, but what price is he willing to pay for the glory? This book was the winner of the prestigious Carnegie Medal.
