Pickerd this up in ASDA out of idle curiosity and having nothing to read. It was the most incredible book - about a girl who is born to save her sister's life and at the age of 13 sues her parents for medical emancipation. I thought it would be fairly stereotypical when I got home and read the blurb properly - but it wasn't. It was very thought provoking and very unexpected. I read the last 2 chapters in the bath, which was just as well because by then I was howling! This doesn't give anything away. So, buy it and enjoy!
