Ooh, this is going to be fun!
I'd like to nominate Gone with the Wind
by Margaret Mitchell:
Sometimes only remembered for the epic motion picture and "Frankly ... I don't give a damn," Gone with the Wind was initially a compelling and entertaining novel. It was the sweeping story of tangled passions and the rare courage of a group of people in Atlanta during the time of Civil War that brought those cinematic scenes to life. The reason the movie became so popular was the strength of its characters--Scarlett O'Hara, Rhett Butler, and Ashley Wilkes--all created here by the deft hand of Margaret Mitchell, in this, her first novel.
I might make some more, depending on what others post up.
