I like all of Jodi's books, but this is just so good. Yes ending is shocking but then the whole subject of farmed children is. I love the way Jodi pick a very TABU subjects and speaks about it loudly - she makes people talk about things they would never have thought of before. I applaud her for that. This story of a girl that has been scientifically concieved to be the perfect donor for her already ill older sister. The twist and turns in this book are great and all charakters involved are very well pictured. This is one book everyone should read.
