I just finished Absolution Gap by Alastair Reynolds.

Absolution Gap is the fourth book in the series started with Revelation Space, wrapping up the stories of most of the characters and the battle versus the Inhibitors.

Overall, it is excellent space opera, though the book might have been better divided into two, since it is so long. The book starts off with three alternating timeframes, then reduces to two for the rest of the book. It also introduces characters and settings in the beginning to have them wrap up very early in the book, in an abrupt way.
