Two things I do well in books are sex and violence, but I don't want gratuitous sex or violence. The sex and violence are only as graphic as need be. And never included unless it furthers the plot or character development.
It is a very natural human trait to destroy that which frightens us.
Perfection is an unattainable goal. It isn't going to be perfect. Just get words down on paper, and when you stumble to what you think is the end of the book, you will have hundreds of pages of words that came out of your head. It may not be perfect, but it looks like a book.
Now that I'm being very successful, publishers are trying to mainstream me, but I'm unabashedly genre. It's what I like to read, what I like to write.
My writing style is very sensual, as in sensory detail.
I try not to worry about rewriting books that worked well the first time. I'm too busy writing new books to worry about things that are already in print.
