I read this book with patience, then after watching the movie I felt I had to re-read it again. It is a brilliant book,raising a lot of interesting questions. I am avoiding on purpose the link between the topic of cloning and reality, because if one has to bring this up then it becomes totally non-sensical. And the latter is not because of what some reviewers are saying, but because of the simple fact that if science was able to find ways to clone a complete human being it sounds illogical that it was not able to find ways to clone just human organs. Cloning human organs seems much more efficient,and removes all moral dilemmas, but then there is no story line. Then, so what if it is non-sensical. It is a beautiful story, excellently written,revealing beautiful characters, and entangled stories.
