So this novel is a post-apocalyptic novel, huge in scope (and page count ~ 950 pages). Nuclear war wipes out most of the world's population and survivors are forced to, well...try and survive. Inevitably, this novel is compared to Stephen King's "The Stand" and fans will argue over which is better. I choose not to argue with myself over that issue; nothing wrong with putting both up on that highest of pedestals. But one can also make comparisons to just about any other post-apocalyptic novel or even such classic works as "Lord of the Flies".
The novel is filled with unique characters, many of them playing tiny supporting roles that turn out to be vital to the overall tapestry. The handful of major characters are each fascinating figures and whether or not they are fulfilling a "good" or "evil" role, the reader can still empathize with them. Many times we're not sure exactly who is a "good" character and who isn't, while at other times, it's crystal clear. In fact, trying to determine where individual characters lie on the Jedi/Sith index is half the fun.
The novel covers the gamut of emotions. At times the violence is raw, brutal, and horrific while at other times we're treated to the amazing beauty of characters' souls. At still other times, there are elements of the supernatural that enter the plot, elements of spiritual powers and faith against the force of evil. The plot weaves brilliantly among different points of view, and, despite its length, I never felt it was too long or that the story dragged. The ending is incredibly satisfying and after reading that last page, I felt like I had been holding my breath for the last hour and could finally release. It's that kind of reading experience.
If you enjoy post-apocalyptic novels or end-of-the-world novels, then this is a must-read. If you enjoy McCammon's writing in general, then this is a must read as it is considered one of his best. For me, it's one more notch in my McCammon belt and I am so so happy that there are still many left to read.
