#10 Different Seasons
I intentionally tried to leave King's many collections of short stories out of my rankings, but found it impossible to exclude Different Seasons  from consideration. This book contains four separate novellas--each corresponding to a general thematic colloquialism about a season.
In Different Seasons, King not only delivered what I believe to be his all time best short story, the incomparable Rita Hayworth and the Shawshank Redemption, he also spun memorable yarns like Apt Pupil--about a boy who discovers that one of his neighbors is a Nazi war criminal living in hidden seclusion in the US--and The Body, a story that most casual King fans would recognize as the basis for the movie, Stand By Me.
All three of the above stories were adapted into major motion pictures. The fourth, The Breathing Method, is a classic Gothic horror tale in the tradition of Edgar Allen Poe, Joseph Conrad, and H.P. Lovecraft.
