Good, but read Mad Mick first?

I feel like it’s a good story which is why I’m on the 3rd Boxed Set. Book 9 is frustrating because there is a 10 minute recap of books 1-8. That, I can excuse since in theory since the author wants books to stand on their own. But come on, we are 9+ books in.
Why do I say 9+? Because I don’t know, at least one book, but likely more since there are whole characters missing in 9 and only vague references to a story that is all about Mad Mick. I’ve stopped book 9 but a little heads up would have been nice that I missed a whole series.
in all the time talking about books 1 to 8, you couldn’t slip in “Hey btw, go read these other books first, because we are gonna basically give a ton of spoilers for that series that you don’t know exists.”

Seems like something an editor should have caught.
