I wouldn't have finished this if I hadn't promised a friend, but that I said I really enjoyed the last part of the book. It just took a very long time to get there. I didn't really like the central them of the 7 Eves and how their one-dimensional characteristics persisted for generations. But I did really like the plot especially the reintroduction of humans to a changed Earth. I skipped over a lot of the orbital mechanics descriptions.
