I've been called to attention that in the first and parts of the second WOTD books that Jasper will occasionally nickname Killian "kid," which, is obviously definitely suspect and not great. It's something I'm changing in the rewrite and I'll say now that Killian is 22 at the start of the series and Jasper is 25. At the time when I originally wrote the story I had a lot of unresolved trauma and so a lot of things I thought was normal in romantic relationships definitely was not. Since then I've been to therapy and have realized those things aren't appropriate at all.
I really hate and loathe that I wasn't able to see that while I was writing it in the past and I'm working on going back and editing/changing it. If you see it then please comment on that paragraph so I can go back and correct it. I'm also not going to have any of that in the second draft I'm working on as I'm looking to self-publish in the future.
If you read all of this, thank you. I hope clearing this up will help people better enjoy the story now and I sincerely apologize if any of those instances have caused people discomfort.
