Yet another Sci-Fi Book Club selection, I picked this one up blindly, mainly because I saw that it had three books (the entire series supposedly) in one. Dawn, Adulthood Rites, and Imago.
This is a great story, well told. It is about the last of mankind after they had destroyed themselves. They awake to find they are on a spaceship controlled by aliens. The aliens need to coexist with humans to survive but it alters humans. Many humans revolt, many stay with their new alien friends.
A great trilogy, what a find! The book Xenogenesis doesn't seem to be available anywhere other than the sci-fi club, but you can order each one separately.
