It starts in a school which has guardians rather than teachers and you slowly get the impression that there is something unique and about the children and the school. They are visited every now and again by a Madame who takes pieces of art they have created away.In the second part some of the characters in the book are now living in a house in the country. You have the sense they they way that have been bought up has made then dysfunctional and awkward. They pair off, but these are not true relationships. Some of the older ones start to leave to give donations.In the final part two of the original characters are together as as a carer and donor. They have managed to make something of their lives, but there is still the donations that Tommy is doing. He has donated three times, but is approaching his fourth, when he completes. They manage to find one of the original guardians and Madame and have some of the questions answered.A strange book in lots of ways, it's beautifully written, but the underlying story of being clones for organ donation is never voiced.
