CC: Thanks for joining me Jeremiah, and congrats on your debut novel! Tell us about it!
JF: Thanks, and I appreciate you inviting me to join today! Here’s what you’ll find in my novel CORE Deception:
A tyrannical government, a cryptic letter, a devious hacker…

In a world where the government’s CORE systems see and track everyone, seventeen-year-old hacker Seth Alvarez is determined to save his sister from being placed in a reeducation facility. Armed with a cryptic letter, Seth embarks on a search for the valuable incognito devices—cyber master keys that can set his sister free. But with only three weeks remaining, he finds himself wedged between two powerful forces who will stop at nothing to get the devices first.
CC: That sounds exciting! I love books about siblings (I have 6 myself!). And congrats on making it to the finalist stage in the debut category at the 2025 Realm Makers Awards! What do you love most about this story and what are you hoping readers will connect with?
JF: I love stories of espionage, undercover, and page-turning suspense. I also like some level of technology. A dystopian setting offers the perfect venue for teen characters to get into these activities. If you love clean YA read that keeps you turning pages, stories of underdogs standing up to dystopian governments, and plots filled with intrigue and suspense, CORE Deception is for you.
Take codes and ciphers for example. I’d read about them in true spy accounts and liked the idea of incorporating them into the CORE Series. As I learned more so I could write about them correctly, I really enjoyed codes and ciphers. In fact, they play key roles in CORE Deception and its prequel novella Association. I even created a Code and Cipher Guide to go along with my books.
Another reason I like CORE Deception is the primary thematic element, which grew out of 2020 when I faced fears I didn’t know I had. I’ve struggled with fear of acceptance, fear of failure, and fear of incompetence before—to name a few fears. But this was new to me. It was fear that dominated my thinking and tried to control my actions. (And really, doesn’t all fear do that?)
Something told me this wasn’t right—more like Someone. As a Christian, I shouldn’t fear like that, not if I believe the Bible. After all, our future is secure, no matter what happens to us physically. And as Christ-followers, we have more hope than anyone else.
So why was this fear so strong? Later I came across a quote by Max Lucado from his book Fearless. He put it really well: “Fear, at its center, is a perceived loss of control.”
That was me. It felt like I’d lost control of almost every aspect of normal life. Not that I had control in the first place. And that was the foundational deception of my fear. Experiencing this it was painful because it forced me to face a reality—I wasn’t trusting God like I thought I was, like I wanted to think I was. But as painful as that was, it was a gift, growing me as a Christian. And I soon incorporated it into CORE Deception.
CC: That’s such a powerful way to put it. I’ve certainly struggled with that. It’s easy to “trust” God when everything is going well. How else has your faith shaped this story? Could you share what “Christian sci-fi” means to you?
JF: Faith should shape everything Christ’s followers do and think. It’s easier said than done, but that’s what I try to do, including with my writing. This doesn’t mean there’s a Bible verse on every page, but it does mean my writing should reflect a Christian worldview and be done for Christ’s glory.
This reminds me of a pivotal point years ago. I’d been writing it since I was a kid, mainly for enjoyment but with the possibility of publishing eventually. I sensed a challenge from the Lord regarding my time used in writing. If I was going to spend time on it, I should use it for His glory and not just my personal enjoyment. Yes, I want to write engaging stories that whisk readers away into an amazing world of fiction, but I also sensed the call to use my stories to “lay up treasure in heaven” (Matthew 6:20). That includes reflecting biblical worldview and weaving in themes that inspire courageous living for God, regardless of the genre.
I like to think of Christian sci-fi—really any genre—as stories written from a biblical worldview. The Bible should always be the foundation and guide for creators and readers. As 2 Timothy 3:16-17 tells us, God’s word is sufficient for all areas of life.
CC: Amen! What did you most enjoy about writing your book? What was most challenging?
JF: I absolutely love the phase of writing when the spark of an idea grows into something bigger. It’s that phase when I’m exploring characters or a storyworld (or both!), ideas explode, and it seems anything is possible. It’s like receiving a fascinating new toy on Christmas Day—I’m just so excited to play with this new idea and see what it can do! With CORE Deception, it didn’t take long to realize I had enough for more than one novel.
But for all those loose ideas to form a cohesive story, I eventually had to put it into a framework (either before or after writing the first draft). The phase of structuring everything, making my setting consistent, and refining character arcs posed one of my greatest challenges. I’ve polished words before and cranked out many drafts over the years, but pushing a novel through developmental edits (making all the large pieces work) wasn’t something I’d done before and was harder than anticipated. But the story is so much better for it.
CC: Worldbuilding is definitely the fun part! Actually sitting down and writing takes so much discipline! How long have you been writing and how did God guide you into this career?
JF: One of my first stories was a one-of-a-kind picture book I wrote and illustrated myself as a kid. It was four pages long with a grand total of seven sentences (if you include “the end”), put together with construction paper, masking tape, and staples. [optional: insert picture below] The name was Twenty Door Bells. A real page-turner, huh? You can tell I was using cutting edge print-on-demand technology too. But you can see my imagination was already at work.

Mostly, I only wrote creatively when it was required for school. But somewhere along the way, I found I liked crafting stories. Sometimes it was because my siblings were writing stories. Later, it’s more likely that I ran out of stories to read, and so I decided to write my own. I enjoyed it so much I kind of became an overachiever with writing assignments.
For example…
Assignment: 5 pages of fanciful fiction
Completed Project: 39-page story of animals in a medieval kingdom, complete with intrigue and major battle scenes.
Assignment: Short story with dialogue (short, as in, only a few pages)
Completed Project: 35-page mystery with black-cloaked thugs and a pie fight, among other things.
Soon I was writing even when there wasn’t any assignment—short stories, poems, novellas, novels—and sharing them with my family and friends.
I got into westerns, action, mystery, humor, sci-fi, fanciful, fantasy, retellings, and even an interactive mystery-thriller. I did flash fiction, short stories, novelettes, novellas, short novels, novels. Having siblings who wrote helped a lot, offering camaraderie and some friendly competition. I have terrific memories cowriting with my brothers and sisters. Also, it was huge that my mom (and homeschool teacher) fostered creativity.
As time went on, I sensed God calling me to do more with my creative writing, as I mentioned above.
CC: Haha, I love your enthusiasm! And that your mom kept your first story! How would you describe your writing style and how has it evolved since those early stories? Do you have any advice for writers as they try to develop a unique style?
JF: I love stories with high suspense, action, and thriller pacing. I think a lot of teen guys would agree. When I read books in that genre, I’m able to detect a general style, especially for action and suspense scenes.
But when it comes to developing my own style, I’ve largely followed James Scott Bell’s advice on the subject. Keep in mind, both he and I write for the commercial fiction market, not literary or what your high school English teacher taught you. In Revision and Self-Editing for Publication, Bell says, “It’s best to allow voice and style to emerge naturally in the telling of your tale. Attend to the fundamentals of the craft, and voice and style will seem organic. That’s your goal.”
Put another way, don’t think too hard about style. As you write more and more, you’ll naturally develop one of your own. But if you concentrate too much on style, you risk awkward, unnatural prose that jars the reader.
CC: That’s a good point. Sometimes writers can over-plan, rather than letting things develop organically. What was your journey to publication like? Why did you pick the route you did and what kind of challenges did you face along the way?
JF: As mentioned, at some point I pivoted from writing for fun to writing intentionally, like for the purpose of publication. I dedicated myself to the craft of writing and eventually started looking for publishers and agents. But eventually, I didn’t sense any major publisher’s interest in my writing. While a small publishing house might have been, I felt like I’d be doing much of the same work as independently publishing—an idea I gradually liked more and more.
More significantly, as time went on I realized that I would really like to have a say in the final book product. I sensed that God wanted me to influence the story, the editing, the cover, the marketing, and so on. The catch is, I had to learn at least some about all those areas. For example, I knew I should outsource my cover design, but that still requires I understand the norms for covers in my sub-genre and can create a design brief for the designer.
Pragmatically, indie publishing works well in the book industry today. There’s definitely a learning curve if you’re going to do it well, but it’s easier than ever for an author to tackle areas like typesetting and selling directly from their website. And I’ve found I enjoyed the business and marketing parts of writing a lot more than I anticipated.
CC: That must be a relief! It’d be so hard to stick with it if you hated the business and marketing like a lot of authors do!
There has been discussion lately of how few young adult books feature male main characters (outside romance plots). Indeed, it seems like major publishers aren’t interested in these types of stories. Why do you think this is? Are you hoping to reach boys and young men in particular, and how do you hope your book can accomplish this?
JF: Yes, I write for teen guys. Perhaps because as a teen guy, I had a hard time finding books I enjoyed. Thankfully, I did find some, and that’s probably why I ended up writing YA! But more importantly, that’s the genre I sense God calling me to. I still have a lot to learn here, so I’m always eager for resources that help me do this.
It’s no secret to those in the book industry that guys don’t read/buy as many books as girls.
If you look at what the large publishers are producing, the same disparity seems to exist in the young adult genre. Not that there’s anything inherently wrong with that. My guess is they’re publishing what sells. To an extent, it’s a chicken or the egg situation—since not a lot of guys read, few new books get published for them, which leads to fewer guys reading and therefore publishers creating fewer books for that diminishing readership.
Some blame the gaming industry for drawing guys away from books, but my counter to that is “what is it about those games that connect with guys?” There are a number of independently published authors who have figured out how to produce stories guys love and are filling the void left by the larger publishers. Because plenty of young men do like to read, even if they’re not looking for reading material in the same places other people are.
This is a big topic, and this excellent discussion on the Christian Publishing Show is a good next stop.
CC: Thank you! That’s a valuable perspective. What’s next for you as an author?
JF: I’m well into the planning phase of CORE Deception‘s sequel. Readers can expect more suspense and espionage while exploring new facets of the CORE Series storyworld and digging deeper into characters like Seth, Krystin, and Jhalak. The next title and plot are a secret right now, though I’m feeding some insider snippets to those subscribed to my emails. Here’s a teaser for the sequel:
A relentless pursuer.
An unpredictable ally.
The opportunity of a lifetime.
Can seventeen-year-old hacker Seth Alvarez survive a daring undercover mission that could change the course of a nation…or destroy everything he’s even known and loved?
After a third novel in the CORE Series, I’m praying about what to write. Several ideas are pushing their way to the front of the line, and it’s too early to say which one will win out. It could be another sci-fi, a modern thriller, kingdom adventure—you get the idea.
CC: Thanks Jeremiah, I look forward to it! And best of luck in the next stage of judging at the 2025 Realm Makers competition!
JF: Thanks so much for allowing me to join the discussion today!
