Steering the Craft by Ursula K. Le GuinBooks are listed in no particular order, but this is the one I always recommend first.

Dialogue: The Art of Verbal Action for Page, Stage, and Screen by Robert McKee"Story" and "Dialogue" lay a very solid foundation in screenwriting. Comprehensive and practical.Write Characters Your Readers Won't Forget by Stant Litore
Write Worlds Your Readers Won't Forget by Stant Litore I'm generally skeptical of any book series on writing—most tend to beat about the bush.

Check out the entire series here.The Elements of Style by Strunk & WhiteMust-read pocket-sized classic.Exercises in Style by Raymond QueneauIn which an anecdote is retold in 99 literary styles. The only book on the list that is not technically on writing, but it can teach you more than some books that are.About Writing by Samuel R. DelanyNot to be confused with King's "On Writing." This one is much more advanced and insightful. To get a taste, check out About 5,750 Words from Delany's "The Jewel-Hinged Jaw."Daemon Voices: Essays on Storytelling by Philip PullmanGives a lot of food for thought, but more philosophical than practical.Wonderbook: The Illustrated Guide to Creating Imaginative Fiction by Jeff VanderMeerEntertaining, inspiring, doubles as a nice coffee-table book.
