A powerful story about friendship, loyalty and family around this topical and controversial issue' - Guardian

'An engrossing story' - Daily Telegraph

'That's all I ever did - watch and listen. I was always a spectator, never a participant. I didn't call that living. I was alive - but that was all.'

Cameron is thirteen, and all he wants is a 'normal' life - friends, swimming, school, family.

But his life is far from normal. Not every thirteen-year-old desperately needs a new heart because theirs doesn't work properly.

Finally, one doctor offers hope.

Cameron could - if he and his parents agree - take part in a radical and controversial procedure involving the transplant of a pig's heart into his human body.

It's risky. And it's never been done before . . .

While Cameron comes to terms with the idea, he finds the world around him is much less accepting.

But surely everyone will understand that it's better to have a pig's heart that works than a human heart that doesn't - won't they . . .?
