William Gibson's Zero History is, for the first six chapters or so, basically setting the scene. The scene, however, is essentially modern day reality, so I didn't really need six chapters for that. Nothing of interest happens in those first few chapters; I imagine if I kept reading, something would eventually happen, but at this point, I don't really care. I just found this review and enjoyed it more than the book.
I received In Search of the Old Ones a while ago, thinking to learn about the Anasazi. It's not really about the Anasazi, though; it's about the history of the archaeological study of them. So what you're reading about is the cowboys who stumbled across the first cave pueblos, and what happened to the artifacts, and how scholars divided Basketmaker from Pueblo periods, and the author's own explorations. If that's what you want, it's a good book.
