I've read all but six and those are the ones I started reading and lost interest in. There are many great classics left off this list but on other top 100 lists. "The Jungle" by Upton Sinclair, "The Good Earth" by Pearl Buck are missing and "The Egg and I" by Bettye McDonald should be on all the lists. I started Moby Dick many times but never got passed the fifth chapter.
Right now I'm reading "Nick in Time" by Ted Bell. It's great to read to your child at night a chapter at a time. The story will keep you interested as much as the child.
