Most of my series overlap. I prefer to keep my series relatively short. I feel like you can pick up any of my series, see a mention of characters from another series and still know what’s going on. You have to think of all my books as being in the same universe. Hence, the Men of Honor guys know Prophet and Mal knows the Havoc guys and…
Well, you get the picture. 🙂
So the Dirty Deed series really begins when Hell or High Water ends.
For the most part, I lay out the series before contracting it. I like knowing when a series will end, as an author and a reader. Right now, the only series that are open ended are Havoc and Workingman’s. And Bluewater Bay, of course, which is a multi-author series and can extend into infinity. I don’t know how many books I’d be writing for that series.
