 2.5 stars. 
 Never Let Me Go has an extremely interesting premise, and I had pretty high expectations going into it. Unfortunately, those hopes went mostly unfulfilled, and I feel pretty let down by how unremarkable this book was. 
 The first 3/4 of the book is a succession of anecdotes about the narrator's childhood, and with a few exceptions, I found them quite dull and boring. I'm not sure if the purpose of all those descriptions of petty childhood arguments and teasing were supposed to be some revelation about the humanity of cloned kids, but I feel like that could have been discussed much more briefly. 
 For me, the book didn't start to get uninteresting until the final section, the part about Kathy's life as a carer. That was when the book finally began to actually address the complex moral and ethical questions related to the raising of clones as involuntary organ donors, the ideas that I'd been hoping would have been present throughout the story. I really enjoyed this section, especially the evolution of Kathy's relationships with Ruth and Tommy and the meeting with Madame and Miss Emily. 
 In conclusion: I think this would have been a much better and more interesting book if it had focused on the characters as adults, but the first 75% of the book just felt unnecessary and was very difficult to get through. 
 If you were disappointed by this book in the ways that I was, you might be interested in reading The House of the Scorpion, one of my all-time favorite books. :)
