Here at Master Book Builders, I'm known as the "Book Artisan" -- the guy who takes over to help with your book design and publishing steps, after you and Yvonne finish writing, editing, and polishing your book manuscript. As a writer myself, I usually chime in with a suggestion here or there.
Since reading your book is inherent in my layout process, I bring that understanding of your message to your cover design, as well.
And then I help with many of the tech and "author business" tasks in the publishing and marketing phases, constantly learning as the industry evolves. I try to share some of that learning in my blog posts, too.
