Why did you choose to write in your genre?

I’ve always written fantasy. As a kid, I grew up with Sailor Moon and Dragon Ball Z. Indiana Jones and Han Solo were my first-ever crushes (and obviously Harrison Ford is real cute too!) World of Warcraft became popular during my adolescence, and Halo too (I suck at shooter games, so I didn’t get into that one). I’ve always had my head in the clouds. Reality is very boring to me; I haven’t had the best of luck existing within reality. I’m forever looking for more, trying to find some meaning for existence. I can find that in fantasy, and I can create the coolest of characters inspired by all the fantastical things I’ve consumed over the years. 

Are you a full-time or part-time writer, and how does that affect your writing?

When I started this series, I was a part-time writer. I have since become a full-time writer, and it’s allowed me to do so much more within my community of readers. I always made sure to have time for my books, but now I have ample time for my readers as well. I like to make sure I am interacting with everyone to the best of my ability within the confines of my story, so more time has been a very wonderful change. 

What role does research play in your writing?

For the most part, I write about things I know or can easily imagine. I focus heavily on the characters, and my background with mental and behavioral health helps tremendously. But sometimes I write things that I don’t know; the later installments have been very modern combat-heavy. I’ve had to research bomb equipment, sniper information, medical procedures, etc. 

I frequently refer to my DSM-5 when I’m writing. I know quite a bit already, but I usually have it available for reference. Especially when writing the end of Lightbringer (The Eôṅśa Book 3), I needed to make sure I was writing things correctly and in the correct terminology. I’ve written reports in case files before, but I’ve never written a full psych report, so it was a very slow process to make sure I did it justice. 

What advice would you give to aspiring authors?

I see so many people becoming upset with their readers if their work isn’t universally loved. This is very strange to me. The entirety of humanity cannot all like the same things; our differences of opinion are what make us beautiful. You, yourself, do not like everything you’ve ever seen. Go into this journey knowing that people are going to dislike your work. People will pick it apart, make assumptions, and be incorrect at times. This is ok, and it is nothing to get upset about. Imagine a world where we were all exactly the same… how boring? Do not get upset at the humans around you for being human when you’re a human too. As long as you like your work, that’s what matters. There will be plenty of people who love what you create, and that more than makes up for the negativity you’ll occasionally get.

Can you share a little bit about your latest book? 

Voidwalker: Deep Cover (The Eôṅśa Book 5) is publishing on December 27th, 2026. It follows Selena as she goes undercover to carry out a rescue mission, and simultaneously follows another character’s slow descent into madness. Secrets are uncovered, and the events of the previous books are called into question. This series is meant to make readers question what they think they know, and this book delivers us right into uncertainty. 

I cannot say much else without spoiling everything!

Who is your favorite character in your book and why?

I have three, but I will name them by their domains instead of their names to avoid full spoilers. In no particular order: Valor, Destiny, and Ruin. 

These characters, to me, are the most fun to write and the most interesting (sometimes tragic) stories. They challenge me as a writer, especially the only female character on the list. It is supremely hard to keep everything together in a mostly cohesive way and to provide a timeline for my readers that makes sense. Also, the interactions between them are some of the most rewarding to write, though of course they are not all neat and pretty interactions. 

Who is your least favorite character and why? 

Again, domains, not names. I’m going to get a lot of hate for this, but Justice and Storms are my least favorite characters. They are easy to write, and I know them very well, so they are boring to me. This doesn’t mean they are bad characters (they are reader favorites), but to me, they just aren’t the best ones I’ve got. 

What is your next project? 

I am beginning to draft book 6 (publishing June 2027), and this one will be the hardest for me to write. I can’t say why without a major spoiler, so I’ll leave it at that. 

Additionally, I have begun work on The Eôṅśa Fanthology. I’ve invited readers to create their own fanfictions and fanart based on the information in books 1-3. It’s going to be a lot of work, but community is extremely important to me and to my project. I am happy to say that I’ve got a handful of people already on the team and in the beginning stages of churning out a piece of storytelling history. We’re looking at a summer 2027 release, but please do not hold us to that!

And I am always working on my Instagram, which is canon and serves as an entry point for readers to join the story.

Who is your favorite fictional character and why?

Yuna from Final Fantasy 10; you’ll see her staff is tattooed on my right hand/arm (very unfinished) if you see a picture or video of me. Her story feels very similar to my own. She begins the game trying her best to be who she thinks the world needs her to be. By the end, she has learned to think for herself, to stand up for what she believes is right even if it isn’t the way the rest of the world thinks. She quite literally helps the souls of the dead transition into the farplane (the afterlife, whatever you prefer to call it), and most of my career was spent helping people find peace within their lives here on earth. She is, in my opinion, the greatest hero character ever written. That particular game is my favorite story ever written too, so I suppose I am biased. But her journey is so beautiful to me. We should absolutely fight for life and happiness and truth, and we should not blindly bow down to establishments just because they are established. Challenge everything, think for yourself, and above all else, live by your morals.
