If you're considering contacting me to ask that I review a manuscript, provide advice about publishing, or endorse a book, I must respectfully ask you not to do so. I cannot be of help to you in this way. In regard to input about whether something is publishable, it is really only a publisher who can tell you whether or not it is something they want to publish. I only consider endorsing books that are written by people I know personally.
My best advice to you is to use this book proposal guide to create your book proposal to submit to a publisher. Working your way through this proposal guide will help you to understand what a publisher is looking for and help you to organize your thoughts and dreams about writing a book. Michael Hyatt, the author of the book proposal guide also offers lots of great publishing advice on his popular blog to authors as well as a list of agents.
You can make your manuscript available to a number of Christian publishers for consideration through a couple of different services: The Writer’s Edge and Christian Manuscript Submissions. This will get your proposal in front of some publishers that you will not be able to contact on your own since they don’t accept unrequested submissions. The big difference is the Writers Edge evaluates your submission and indicates whether or not it is publishable and Christian Manuscript Service does not evaluate the submissions but allows you to put up a 1,000-word description on its secure website.
While only a few years ago I would have never recommended that someone pursue self-publishing a book, the advance of technology that allows for smaller print-runs, and the proliferation of the internet to get your message out has really changed that. Several places you might check on in regard to self-publishing include: Westbow Press, Crossbooks, and Xulon Press.
When people who have a story they want to tell ask my advice about writing a book, I often suggest to them that they first consider writing an excellent article and seek to get it placed in a magazine or on a popular website or blog. This helps you to refine the telling of your story and the key "take-aways" or points you want to make with your story. It serves as an outlet for your desire to minister to others with your story and as a reality check in regard to the interest those who are not connected to you will have in your story. You might also look at my responses to a couple of people in the Ask Nancy section of this site. But the most important thing I would want to tell you is this: the most important thing about telling your story is that you use your story to tell God's story.
