I've been freelancing for many years and have been focusing on fiction in the past few years, as that is what I like to read myself. My preferred genres include mystery, science fiction, fantasy, and historical novels. I'm able to combine expert knowledge of American English with sensitivity to plot, character development, logical progression, and historical accuracy. I'll copy edit your book and then review the changes in a second reading for a small additional fee. Upon request, I'd be happy to review your query letter as well. Even if you're a first-time author, you can offer agents and/or publishers a professionally edited manuscript and set yourself above the mass of submitted projects without such polish.
