When I started writing to make a living, I ran across a post that said authors need to write between 15 and 20 books to be able to make a living from their writing. The idea is that people buy a new release, like it, and then buy the other books in the author’s backlog. One crucial piece of information that I missed was that these books should be interlocking trilogies, so three focus on main characters and the other six focus on side characters. No matter, I thought about the type of book that I enjoyed the idea of, and the Nancy Drew and Hardy Boys series (affiliate links) came to mind. Then I crafted “the Adventures on the Amur.”
