Book Feature: The Light of Arunzi by Katelyn Peterson

What Happens When a SWAT Negotiator Inherits Two Magical Orphans

(By Justine Castellon / for Just Reading Nook)

Have you ever picked up a fantasy novel expecting a chosen kid and ended up rooting for a stocky, balding, middle-aged cop instead? That’s what The Light of Arunzi did to me. It’s the debut novel in Katelyn Peterson’s The Magois Chronicles from Convergence Point Press, set in modern-day Toronto, where tactical police work and aristocratic magic share a city and do not get along. A hostage negotiation leads straight into a 3:00 AM knock at Greg’s door. From there, it turns into a story about who protects the helpless, and what that costs the protector. There are lion cubs, magical foals, and noble houses with long memories. But the heart of this book is a sergeant with a very bad habit of putting himself last. I have thoughts. Let’s get into it.

So, What’s It About?

I’ll keep this spoiler-free, because the fun is in how it unfolds.

This is Toronto, but not quite ours. It sits inside the realm of Albion, where spellcraft and modern technology live side by side under a lot of tension. The social ladder is simple and ugly. At the top are the magois, aristocrats with inborn magical power and authority over everyone else. Below them are the techies, non-magical humans who rely on technology, modern weapons, and ordinary police structures, and who get looked down on for it.

Then there are the alaetans, and this is the detail that stuck with me. They’re the non-magical children born into magois families. Without enough active magic to cast, they’re cast out of magical society to live among techies, and their bodies age at an accelerated rate. Sit with that for a minute. It’s a society that throws away its own kids because the magic didn’t take.

Our guy is Sergeant Gregory “Greg” Ryder, a techie and a negotiator who leads Télnis Aonan, an elite squad in the Strategic Tactics and Response division (STAR). After a high-stress hostage call downtown, a magois official knocks on his door at 3:00 AM. Greg’s distant relatives in Britannia, Lord Artorius and Lady Victoria Calvin (Lord Calvin was the Queen’s Right Hand), have died defending their ancestral manor. Lord Calvin’s will names Greg, a non-magical police sergeant, as legal guardian of their two surviving children.

Meet them. Lancelot, called Lance, is thirteen and the Scion and Heir of House Calvin. His younger sister, Alanna Victoria Calvin, is a Scion too. They arrive grieving, carrying real prejudice toward “techies,” and bringing two Mage Guardians: Lance’s lion cub, Elektra, and Alanna’s alaricorn foal, Sunstar. Mage Guardians connect directly to human spirits. They shift between soft, stuffed-animal forms and living magical beasts that can throw up elemental shields. I love that detail.

Greg opens his home and invents a temporary foster cover story for his team. Meanwhile, the children’s uncle, Lord Cyrille Torrance, wants custody and control of House Calvin’s legacy, and he is not the type to ask nicely.

Around Greg is a squad worth knowing. Ed Logan is the sniper and tactical leader, fighting a mind-control compulsion planted by a rogue lord. Endeavour “Dev” Winner is the lean peacemaker. Scarlatti, called “Spike,” handles tech and computers. Wordsworth, “Wordy,” is the muscular veteran with old baggage from a magois encounter involving his brother. Jules is the second sniper and profiler. And Sam Bradagan, a former JTF2 sniper, is the rookie. That’s a lot of names. Hold that thought, because I’ll come back to it.

Is It Really the Adult Harry Potter?

Let me be upfront: this is a comparison I’m making, and I’ll tell you where it holds and where it doesn’t. It holds in some very specific places.

Start with the bones. Two orphaned kids from a powerful magical family land, in the middle of the night, with a guardian they’ve never met. A class system runs on who has magic and who doesn’t. The kids come with magical companion animals. An ambitious relative wants what those kids represent. And a dark curse can take over a person’s mind. If you grew up on Harry Potter, you’re already nodding.

Here’s the flip, and it’s why I think the label earns its place. In Harry Potter, the non-magical guardians are the villains of the opening act. Here, the non-magical guardian is the hero. Peterson takes the person the magical world treats as an obstacle and makes him the one worth trusting.

She’s honest about where that comes from. In the interview, she says she’s been telling stories “as long as I can remember,” mostly crossover fanfiction. Chronicles of Narnia, Harry Potter, and The Lord of the Rings wandered into CSI, Law & Order, and Criminal Intent in her head. She even admits to a phase of imagining Shadow the Hedgehog as a part-time Jedi and Keyblade Master. So this book didn’t come out of nowhere. It’s what happens when a kid who mashed Harry Potter into cop shows grows up and writes the mash-up properly.

One fanfic she points to is “Muggle Summer, Wizards’ Fall,” and what stayed with her was the idea of Harry teaming up with non-magicals. In her words, “the core theme of Harry partnering with non-magicals in his fight against Voldemort is an amazing tale.” She also picked up BBC’s Merlin on DVD later. She notes the non-magicals there were “pretty much hopeless” without Merlin, but the rare moments he could openly help against a magical threat were “just so cool.” In this book, the non-magicals are not hopeless. Greg’s people are trained, disciplined professionals who show up for every hot call.

The adult part is about who carries the story. Harry is the kid. Here the grown-up is the lead, and the kids are the ones who need him. The stakes are grief, custody, and the legal system: a fight over guardianship, warrants that can be rigged, and a villain who plays dirty with curses and bombs. It reads less like a coming-of-age and more like a responsibility story.

Now the asterisk. There’s no school here and no chosen-one prophecy. The tone leans procedural. And it’s the first book of a series, so the world is still opening up. Call it Harry Potter for grown-ups if that helps you find it. Then read it for what it actually is.

The Lesson Greg Has to Learn

The book opens with an epigraph from WWII spymaster Sir William Stephenson: “The simplest acts of courage are those which defend the helpless.” Peterson says that line is Greg’s philosophy from page one. “At his core, Greg is a protector,” she says. He protects his team, the victims, and “even tries to protect the criminals.”

He can’t always pull off all three, and he knows it. She says it still burns him when he fails. That’s why he drives his squad so hard on training and works to truly connect with the person on the other end of every call.

Here’s the catch. Greg doesn’t apply that same protective value to his own life, which she says “frustrates his teammates to no end.” She’s careful to say he isn’t reckless for the sake of it. But given a choice between himself and someone he cares about, he picks the other person every time.

So what’s the lesson? Peterson lays it out cleanly. Greg has to “mature to the point of letting his teammates help him uphold that philosophy in his personal life.” And, ultimately, “letting the kids help him in areas where they have skills (and he doesn’t).”

I love that second part. It quietly flips the epigraph. The children are the “helpless” Greg is defending, but they’re not helpless at all. They have skills he doesn’t. The lesson is that protecting people doesn’t mean standing alone between them and the world. Sometimes courage is letting someone stand next to you. Anyone who has ever been the “strong one” in a family or a team knows how hard that is. Protective people are usually terrible at being helped.

That’s where the book’s themes of duty, redemption, and found family come from. Greg’s team has to trust him. The kids have to trust a techie. And Greg has to trust them back.

Okay, But How’s the Writing?

Peterson’s approach is right there in her answer about balance. For her, it’s “less about balancing the police negotiations with the fantasy and more about weaving the overall story threads together.” She wants both sides to feel as authentic as possible. Her method is to spring off the cop shows she’s watched for years and find spots where magic can “twist” the outcome, for the good guys or the bad guys.

And then this line, which is basically her whole craft philosophy: “I let my cop characters be themselves, regardless of whether they are on a hot call or dealing with the magic that suddenly invaded their lives in the form of two young orphans.”

You can see it in the structure. The narrative moves between tactical work, including arms evaluations, hostage negotiations, and sword training in tech-dampening “magic zones,” and quiet domestic scenes where Greg and the kids figure each other out. The point of view alternates. You get Greg’s protective instincts, the team’s internal struggles, and the children’s view of adjusting to non-magical life in Toronto.

The novel is dedicated to the Canadian police drama Flashpoint, and it shows in the ensemble approach. Peterson loved that show’s team and its cops “doing their best to bring everyone home alive (even the bad guys!).” That ethos is Greg’s. It’s the difference between a cop story where the squad is background noise and one where every member has their own baggage and their own arc.

Now for my honest heads-up. The cast is big. A seven-person squad, two kids, two Mage Guardians, a family advisor, a commander, and a scheming uncle add up to a lot of people. Add the world’s vocabulary, with magois, alaetans, kitsarion, pavarian, and télnis, and you’ll be carrying a mental roster. If you like your worlds introduced slowly, give it a couple of chapters to settle.

Who Should Pick This Up?

If you love ensemble stories in the Flashpoint mold, this is your book. Same if you like urban fantasy where technology and magic clash, found family, or heroes who are tired professionals rather than teenagers. And if you’ve been hunting for something to scratch the Harry Potter itch as a grown-up, here you go.

If you want whimsy and wand-waving, adjust your expectations. This is tactical, and it sits with real grief. Expect hostage situations, mind control, and orphaned kids working through loss.

So, Should You Read It?

Here’s my honest take. The Light of Arunzi asks for a little patience up front. The cast is big, the vocabulary is heavy, and you’ll be juggling names for a while. But it pays you back. Greg Ryder is the kind of hero I want more of: a non-magical cop who shows up, does the work, and slowly learns that protecting people doesn’t mean doing it alone.

It’s Harry Potter for grown-ups with a badge, a found family, and a real question at its core. What does courage look like when you have to let people help you?

Do I recommend it? Yes. Read it if you love ensemble stories, urban fantasy, or a hero who is tired, stubborn, and good. Just give the world a couple of chapters to settle. And I’ll be watching for what Peterson does next in The Magois Chronicles.
