Is this Hawthorne University? Same place different characters? Or same characters earlier time in their lives?
Yes, it's the Hawthorne University Witch series. I have books 1-6 done with two short stories. Alondra--see my blue cover in my signature--has already been published as a prequel. It has the same university setting but with my MC's teacher, Alondra, as a student. My idea is to write two additional books and change the Alondra prequel into an additional series. Then, bingo, I have another linked trilogy to my series.
The trouble I'm having is retaining the series title linking. I think something with, either Alondra, or "early years", or something added, would help. My original thought was to just write "Alondra series," but retaining Hawthorne University Witch... would probably be better.
But how do I retain the series links? One idea would to link it to the original series would be to take titles publish them with a number. Something like: "Alondra, Prequel I" (The Hawthorne University Witch Series). Then "The Warlock, Prequel II (The Hawthorne University Witch Series) ??? That would still keep the new series under one primary series on Amazon. But
then it wouldn't be numbered in Amazon's series link feature. So...
Easiest and straightforward is to make an entirely new series, of course. But if I do that, it won't be linked on Amazon to the original series. Then the only link would be in A+ content, like Timothy spoke of^^
Understand, I haven't written these books yet. But, as we all know, it's good to plan ahead. Some of our success depends on the projects we decide to spend our time on.
