Hello, books must have a storyline or universe or characters in common to be a series. "Universe" means the setting. Some of the characters could encounter each other, or, some of the characters are the same in each book. A shared theme is not a series by Goodreads definition. Can you please tell us how this series meets the definition of a series by Goodreads standards? It is necessary we know this information before creating a series, not following the rules can get our librarian rights removed. I was unable to find this information myself when looking up online.
