I just finished "All Tomorrow's Parties" by William Gibson. It reads well. The book is set in the cypherpunk universe that Neuromancer, Johny Memonic, and Idoru are set in, and follows the events of Idoru in time. Many of the characters and concepts are familiar to readers of the other books, but the book stands well by itself.

The point of view spirals around a very wierd cast of characters including: Colin Laney, a subject in an experimental drug trial that can see change in dataflow patterns in cyberspace; Rydell, a security guard; a mysterious european assassin; Silencio, a mute street orphan with photographic memory; Rei Toei, the Idoru, a pop music star that is an AI.

My only objection is that the book resorts even more than usual in the "chess pieces moved by incomprehensible forces" than other books in the series. These particular pieces end up on the community of squatters on the ruins of the Oakland Bay bridge, where some kind of extraordinary change is about to happen.
