I enjoyed Stephen King's "Different Seasons" for its novella "Rita Heyworth and the Shawshank Redemption" upon which the movie is based. A great story about friendship, persistance and hope.
"The Painted Bird" by Jerzy Kosinski. A horrific graphically violent story of a boy on his own in Poland during World War 2. A dark commentary about human beings in general.
A collection of short stories by Ernest Hemmingway, especially the story "The Short Happy Life of Francis McComber" about a person gaining control over their life.
"The Stand." Good vs. Evil with the last of remaining humankind after Armageddon hits the world in the form of a CIA-created virus.
