I was really surprised by this book. Egan used the techniques well, without falling into post-modernist cliches. The interweaving of the characters and events really worked. Like the goopy, thick brushstrokes of an impressionist painter, we somehow see the subjects better through this type of lens.
Rather than a standard, linear storyline, Egan provides the reader with a cognitive pop as we recognize a familiar character from a previous (or future) time. The reader takes a secret pleasure in knowing something about that those in the chapter don't. This technique produces more visceral impact than I would have believed.
A hip, intelligent read.
