Mary DeMuth. She is published in fiction, and non-fiction (including memoir), a popular speaker, and is becoming known for her editing skills at The Writing Spa.
I became familiar with Mary through a writer's loop I joined several years ago. We were able to meet at the Colorado Christian Writers Conference in 2008. I told her then, that she ought to write a book on writing. You'll see why.
Mary DeMuth had an interesting road to publication (I think she"d say it's still interesting!). Would you be willing to write in obscurity for ten years before beginning the process of publication? Mary is even thankful that it took her so long.
She began her So You Want to Be Published? blog in 2007, and it became a frequent stop for writers at all stages. Sadly, Mary's commitments prevent her from continuing the blog, but the two-and-a-half years of archives will stay online for writers to continue learning.
On the blog, Mary and her two critique partners post articles, critiques, and links for writers. Dozens of guest posts from published writers give insights into their road to publication. There are many other popular columns, such as Advice From Pros, where authors and agents share what they've learned. One of my favorite columns is the "I'd be published, BUT . . . " series, where writers tell what's holding them back from publication.
Other great series' are the Nuts and Bolts posts (with great information for newer writers), Your Questions Answered articles, and a large number of excellent articles on The Writing Craft.
I can't tell you how much I've learned from this generous author, and how much her writing has encouraged me. Definitely worth checking out.
