What is there to say about this book. It's big. Like most Stephen King books, it's thick, rich, and meaty. The Stand as originally published was thicker than that. This is the running-off-at-the-word-processor version, so it's even bigger Egads!
The first third of the story is The Plague, a nasty bit of bioengineered human business that wipes out some 99.97% of Erth's population. The remaining two-thirds is the rest of the people trying to deal with this sudden lack of gas pumpers, electrical engineers, and so forth. Humanity (in the US at least -- no word on the Country Formerly Known as the USSR) divides into two camps: Jes' Good Folk up in Colorado and the Nasty Sexy Folk down in Las Vegas. Lots of wandering around the country, lots of people trying to cope with, say, a city filled with rotting corpses and lots of plot. If you can believe it, I read this entire book aloud to someone. It took a while, but it was fun. King even uses "Washing machined" as a verb. How can you not adore that?
