Don't pay attention to the clown who wrote the nasty one-star review. This book was so much fun I didn't want it to end. Survival horror that's truly scary, sure it has some flaws (but what King/Koontz horror novel doesn't!)It's a little dated at times and vague at filling in the blanks as to why it happened,(I'm glad it didn't it places the reader firmly in the characters shoes) this is not a book solely about nuclear war it's a book about fear of the unknown: Trying to survive nature out of control, terrifying gory rat attacks, dissention among each other, along with radioactive fallout, and the contaminated survivors, diseases, injury without a doctor ect. Intense unrelenting action, graphic violence, split decisions with catastrophic consequences, sense of doom and dismay that permeates every page makes for a thrilling read...(The Rats are the real stars of this story) this is not a boring book and it would make a great movie.
