Interesting, sad book that has, really, one of the most misleading covers I have ever seen, but I suppose that's not the point.
A near-future England has raised clones to supply 'donated' organs (is this like Nini Holmqvist's The Unit?) and the clones, as they grow up, begin to understand and dread their futures.
Heartbreaking, beautifully written, and, again, with the damnedest cover. Really no clues as to topic, there, that I see. Maybe the forget-me-nots?
