Ernest Hemingway on Writing...
...and F. Scott Fitzgerald on Writing, both edited by Larry W. Phillips. Very inspiring books, especially for novice writers. I'm in the progress of becoming a prose writer and these books were some seriously high-octane fuel. I plan to read the next ones too:
By Hemingway: Death in the Afternoon, Green Hills of Africa, A Moveable Feast
By Fitzgerald: The Crack-up, Afternoon of an Author
