To begin with, I attempt to write each novel as standalone as possible. I want people to be able to pick up the most recent book and be able to read it with ease and no confusion. For this reason, I often make reference to previous events from other books in quick, digestible descriptions but I try to avoid retelling the story because, for those following my series, I know it could be redundant.
Spoiler Alert! As an example, in my second book in the series, Always be a Wolf, Chase Jacobs loses one of his sons. In my most recent book And the Devil Will Laugh, I make reference to it in a very general sense so that the reader has an understanding however, I don't repeat the entire story. I don't give details like how, why or explain the final resolution. Instead, I make a few broad hints and move on.
Essentially, I want the reader to have an understanding within the context of the new story without having to wade through the previous storyline. I've done this many times and find it's the best method to keep everyone happy. ☺️
The interesting thing about this series is that the first couple of books (We're All Animals and Always be a Wolf) center on the character Chase Jacobs, who tends to be slightly naive about what kind of world he is entering. A young man from rural Canada, his eyes are slowly opened up to the crime world he has joined.
My last three books (The Devil is Smooth Like Honey, A Devil Named Hernandez and And the Devil Will Laugh) has Jorge Hernandez as the protagonist and while Chase is trusting and gentle, Jorge is strong and defiant. It's interesting because not only do you get to discover the contrast between the two characters but also, you can finally see the flip side of the story as you enter the criminal side of the story. I love the fact that there is a slow discovering in the series that allows the reader to see how someone unexpected might get pulled into this dark world.
Of course, I explain this much better in the accompanying YouTube video below.
