At first, I got books out of the library, and later, began buying my own copies of those that worked best for me. I have a huge collection, and the books listed below are my top picks for a writer starting out. And if you want it badly enough, you can get it. Nancy Kress is my all-time favorite writer on the subject of writing well. She inspires me, and I never fail to learn something new when I read her.
Every writer owns a copy, and most get the updated editions every year.
A fantastic look at the Soul of the Storyteller. Read everything, but mostly read the kind of books you aspire to write. You must have mastered basics such as grammar, spelling, punctation before you even begin. No, that's not what editors are for. You must have a understanding of the basics of creative writing.
