Holly Lisle is a fantasy author (two of her books are available for free from the Baen free library) and author of several books on writing. Her popular website has a large collection of helpful articles, writing FAQs, and some great workshops.
I make a full-time living from writing. I know a lot of writers who would like to do the same. So I’ve written over 100,000 words — all of it available for free in the linked articles to your right — on how I do what I do.
