Im looking for the title of a book I read as required reading in 6th or 7th grade in the US. The book was about a nuclear war I think that had virtually killed off the human race, and there are maybe two characters ( I think kids or teenagers) and they are roaming the distroyed world looking for other people. I think they are siblings. I remember at one point they find a radio with a distant signal and someone who is talking and he thinks he is the only one left too... its in my far mind, I can't remember it all. It was around the time we read Fahrenheit 451, the Giver, and of Mice and Men... any help would be appreciated.. IM trying to collect all of these books I loved so much for my sons to read one day. Anyone know of a list anywhere? I can't remember them all, and most of these books they don't read in schools anymore... thanks:)
