I started books constantly in the 1970’s after I taught myself to type on an old Underwood. I still have a lot of those old pages lying around here somewhere in a filing cabinet. The one story that I stuck with and continued to work on all the way into the early 2000’s was the novel that I divided into Orphan and Magician. When I self-published the novel as an ebook on Amazon (and other places) in 2010, the novel had enough success (10,000+ sales 2010 to 2016 and generally good reviews) that I felt the long effort was worthwhile. My writing and interests have moved on from that sort of long form series fantasy, but Orphan still sells occasionally even today.
