Mood is the feeling an author sets in their diction to make the readers feel a certain way (i.e in most of Edgar Allan Poe's work, the mood is usually depressing, angry, or vengeful). Theme is message the author is trying to tell the reader, for example, honesty is the best policy, or not everything you hear is true. This impacts an author's work since it expresses and illustrates the story.
