The book group selection for March 2010 was Never Let Me Go by Kazuo Ishiguro.
Never Let Me Go is narrated by Cathy, a carer. She tells of her time at an exclusive school and her friendship with Ruth and Tommy. Slowly through the book it is revealed that Cathy, Tommy and Ruth aren't like normal people. They have a special purpose. To say anymore would ruin the story. In fact, you should probably stop reading now if you don't want to come across any spoilers.
I was watching Catalyst on the ABC on 1 April 2010, and it reminded me strongly of Never Let Me Go. Perhaps this was how it all started? I think the issues of growing human organs and cloning is still very topical and this book should promote you to think about these issues.
