I am a Margaret Atwood fan, and I am trying to do a "best of sci-fi summer" and I wanted to read this book for the simple fact that she wrote it, but didn't think it fit the bill. Fortunately it did (I would have read it anyway), and I liked it more than I expected to. In true Atwood fashion, there is no resolution, no happy -- or unhappy -- ending [Edit: there's a 2nd book, so there is a resolution. Ish.], but there is a lot of thought-provoking material and all-around great writing that just sucks you in. The story is of a man who seems to be the last authentic homo sapiens on Earth, and it switches back and forth between the present and the past events that have gotten him to where he is now. Really interesting ethically and scientifically.
