This book had a very interesting concept (click here if you'd like to read a spoiler-free overview) and was quite beautifully written, but I'll confess that I found it boring. Not that I have anything against sci-fi. I definitely have a couple sci-fi bones in my body (one of my all-time favorite books is Ender's Game by Orson Scott Card), so I don't think it was the weird "out there" factor of this book I didn't like. It just seemed to be lacking drive and heart. Nothing was propelling me forward and I never felt emotionally invested in any of the characters. There were also a couple significant plot and logic holes. On top of that, it seemed to me that the whole book was one big lecture on the evils of modern medical technology - which I happen to be a big fan of.
