Pattern Recognition by William Gibson
Unlike the Sprawl and Bridge trilogies, this is the first time I've re-read Pattern Recognition. I like it a lot more now, I think, than when I first read it in hardcover from the library. The characters, settings, and plot make more sense to me now than when I read it the first time. He's definitely become more sophisticated in his development of the branding-sensitive protagonist, Cayce Pollard, and his exploration of culture, marketing, fashion, and art (in this case, film theory). The other interesting thing is that this is now a "historical" novel and it withstands the test of time.
The protagonists in the preceding novels of the Bridge Trilogy (Virtual Light, Idoru, and All Tomorrow's Parties) are young people, whereas the characters in Pattern Recognition are all adults. The change in perspective is interesting – I think it's harder to write convincing adult characters (that aren't copies of the writer) because they require more imagination and context. Some of the attitudes in the novel seem dated, but they merely remind us of how much the world has changed since 2002.
You can see in the cover images below that the designers had trouble conceptualizing his ideas (my copy is the upper-left version).
