Nadia and her younger brother Rabbit are alive after their mother die from BluStar, a virus that travels around the world and kills 99% of the population. Their uncle Bean is a doctor who has been working in a top secret project for the government. He has a vaccine that he gave to Nadia and Rabbit, but their mother refused it. He has returned to his father's home across the the country, and when their mother dies, Nadia and Rabbit set out to join their uncle and grandfather in West Virginia. This is the story of their adventures along the way.
I really enjoyed this book - maybe in part because it is not nearly so "scary" as Stephen King's The Stand, and maybe in part that it is general not so full of "bad" people and violence as other books of similar nature and content. Even though there is SOME violence - and some hinted at as well - in the aftermath of this disaster, it is not overwhelming. Generally most of the characters are good people. I'd like to think that most people would be nice in the aftermath of such a disaster.
