Isherwood (Ish) Williams is one of the few survivors of a disease that destroys civilization and all but wipes out humans. This story goes through how he survived, his travels and formation of The Tribe, his initial hopes of rebuilding civilization and his ultimate acceptance that civilization as it once was is gone forever.
I loved this story. Written in 1949, it has stood the test of time with a few minor glitches such as the use of DDT to spray everything from clothes to latrines. The resurgence of strong superstitions was a surprising touch, especially when it comes to Ish and his hammer.
I don't think you will be disappointed in this book.
