Cameron Kelsey has only a few months to live, and is no longer able to play sport, swim or live a normal life in any way. With no suitable human heart donor available, he has an impossible decision to make: to be the first human being ever to undergo a revolutionary new surgical process, or to die before he reaches fourteen. Cam chooses to live, and agrees to receive the heart of a pig called Trudy. What will the consequences for Cam and his family be when the world finds out that he is the first ever pig-heart boy?
