I am drowning in this roaring silence. I am drowning. I'm going to die... Cameron is 13 and desperately in need of a heart transplant when a pioneering doctor approaches his family with a startling proposal. He can give Cameron a new heart - but not one from a human, one from a pig. It's never been done before. It's experimental, risky and very controversial. But Cameron is fed up with just sitting on the side of life, always watching and never doing. He has to try - to become the world's first pig-heart boy.
