First of all, tell me a little about your series and introduce us to the sequel(s).
So my series is Adventures of a Villain-Leaning Humanoid, and it's an urban fantasy superhero series featuring Greek mythology retelling. The second book is Torment and Tarnish, and it picks up after Meg has officially joined Vigilante aka Virgil as the first member of his newly formed team.

Do you find that most of your readers continue to read the whole series? Why do you think that is?  
I would say so, at least, the readers who have messaged me continue to the series, and I think it's because they love the characters and the books themselves are just fun and entertaining to read.

How difficult is it to add new characters in a sequel into already established relationships? 
Oh, gosh, the initial three give the incoming characters such a hard time, so things tend to be rocky between them at first, and Meg as a character just did not want the plot to progress where I wanted it to, so I gave up fighting her on it. In short, it can very difficult, and then some of the characters just slot in like they've always been part of the group, so the mileage can vary.

Is it difficult to continue with worldbuilding for a world you have already built in book 1?  Do you find it easier to switch locations for the sequel and start again with worldbuilding? 
Since I'm just springboarding off what was already there and basically fleshing out what was already known about the world, it didn't feel difficult at all. It was trying to name new locations that was the hardest part of that.

You’ve recently published a standalone, The Sparrow and the Oak Tree. Could you tell us more about it?
So that is a fantasy romance retelling of Tristan and Isolde, and it includes fae, enemies to lovers, a grumpy sidekick/mentor-style character, a too smart for his own good horse, and hordes of the undead wandering willy-nilly about the forest.

Have you ever been stymied by a worldbuilding or plot detail from book 1 that is very inconvenient to deal with or write your way around in subsequent books? 
Not yet. I'm waiting for that to happen. But because I've basically created the entire series in about the space of a year and a half I'm not having to go back and comb through the previous books to remember what I've done. That seems to have made it easier to keep track and plant clues along the way.

Would you say your craft has improved with the subsequent books?
I sure hope it has.

Do you have all the timeline planned for the full series?
I have all 12 books written, and at this point, it's just edits to expand on things and add additional details as well as clarification on events.

Do you have any marketing tips for sequels? 
Honestly, I think you've got to market a series as a whole, even while you've got other books in it in progress, because I find that the teasing toward future events helps catch interest.
