After carefully re-reading "Centennial," I still firmly adhere to my original rating of 2 stars. It's not a terrible read by any means, but it's clearly not Michener's finest work. Just like all of his stories, this one is a multi-generational saga, yet it is set specifically in the town of Centennial, Colorado. The tale commences with an exploration of the area's geology and then guides the reader through the extensive history of the region and its diverse inhabitants, both animal and human, spanning from prehistoric times all the way to the 1970s.
I'm accustomed to Michener's style of commencing with the geology and archaeology of an area. When he writes about the history of a place, he truly covers ALL of it. However, this time around, I found myself skipping over those sections. (I must admit, I'm a bit of a bad reader in this regard!) The book begins with a first-person narrative of a fictional professor who is approached to write about the area for a fictional news magazine. This is a rather minor plot device, but I found it irritating enough that I had to mention it in my review. For one thing, this part of the story is extremely dated. I understand that this is to be expected since the book was written in the 1970s, but it really hasn't aged well and has even reached the point of being almost humorous. The book also concludes with this first-person narrative, which serves the purpose of connecting all the families and characters written about previously to their modern-day descendants. But again, it is still so dated that it becomes rather distracting. Michener employs this device throughout many, if not all, of his books, but it simply wasn't effective enough in "Centennial."
Perhaps the best way to summarize this book is that "Centennial" is structured similarly to most of Michener's novels, but what worked well in his other works just didn't quite cut it here.
