Ruby Dixon has a lot of books released and a good majority of them are connected. Some of those characters do make appearances in the rest of the universe. The Rubyverse is always expanding with new spin-off series, so I’m sure it’s going to be more back and forth. But as of April 2024 here is how the books connect as far as the timeline goes. I have tried to keep this updated with every new release, but sometimes it takes a moment. Not to mention, this is extremely complicated due to how interconnected all the series are, so I’m going to include the flow chart that Ruby Dixon posted on her website and I’ll also try to write it out as well.
