It was pretty okay. Fairly interesting ideas around the nanotech and the role of faith in society. Also, we started with some rather nice prose, but I don't recall being struck by anything further on.
I think the story was marred by having 6 characters, some of whom left me completely flat. I didn't skip over any of the subplots, but found myself eagerly waiting to get back to the "good ones". It just didn't seem like enough of a benefit to justify the effort required to track everyone...
