I wish I could say I made a misstep, but actually I didn't. When I received enough rejections from publishers to fill a wall in my room, I decided to self-publish. I researched all the Print On Demand publishers and chose Book Surge because of their contact with Amazon.com. I followed all the directions carefully, and I must say that Book Surge did a great job.
What would I do differently if I could? I would work harder on getting a publisher; I miss the distribution access and critical review possibilities that publishers provide, but places like Redroom help to fill in the gap.
