Witches, werewolves, ghosts—and those are the good guys! They operate in the dark so we can sleep at night.
When a man vanishes from a Kansas City diner — pulled from reality by forces no one can explain — Nathan Quipp knows it's only the beginning. As director of the Office of Hidden Realms, Nathan has spent his career keeping the supernatural world invisible to those who can't handle the truth. But something is moving even deeper beneath the surface. Ley lines are surging. Cross-realm incursions are rising. And a near-divine source whispers the need to find the missing man — the Eidolon.
Eidolon is the first installment of the OHR Case Files — because it's time to drag KC's hidden world into the light.
A copywriter for over two decades, Stiles has spent his career crafting words for clients who prefer their reality strictly un-supernatural. They frown on the metaphysical in copywriting. He's making up for lost time. Eidolon: From the Case Files of the OHR is his debut novel and the first installment of the OHR Case Files series — bringing the hidden world of urban witches, tech-savvy werewolves, ageless agents and things that shouldn't exist to the streets, diners and river bottoms of KC.
He lives in Kansas City with his wife and three dachshunds, who hold strong opinions about allowing writing to interfere with walks.
⚫️Five stars this is one of those urban fantasies that grabs you right from page one and just doesn’t let go. Eidolon: From the Case Files of the OHR throws you into a world where witches, werewolves, ghosts, and plenty of things that go bump in the night aren’t monsters they’re the ones working to keep the real monsters at bay. That spin on the usual fantasy rules makes the story feel fresh, but it still checks all the boxes you want in a good urban fantasy.
⚫️C. L. Stiles wastes no time pulling you into the action, mixing mystery, suspense, and just the right amount of magic. Nathan Quipp, who runs the Office of Hidden Realms, is one of those sharp, likeable leads who makes the whole ride even better. As the strange cases pile up, you get a strong sense something big is brewing, but there are enough twists and interesting discoveries along the way to keep you guessing.
⚫️The world-building really stands out here. Ley lines, hidden power struggles, and the whole supernatural bureaucracy all come together in a way that’s detailed but never bogs things down. The story moves along at a great pace too there’s action, there’s investigation, and the characters all actually feel like people you want to spend time with.
⚫️If you’re into series like The Dresden Files, The Rivers of London, or The Hollows, this book is right up your alley. But honestly, even if you’re new to urban fantasy, it’s easy to jump in no need to already know the genre.
⚫️Eidolon is fast, fun, and has just enough mystery left at the end to make you want the next book immediately. I definitely recommend this to anyone who loves supernatural adventures or just wants something smart and fresh to read.
Ever wondered what would happen if the FBI secretly handled ghosts, fae, werewolves, and ancient monsters instead of regular crime?
That’s exactly what Eidolon: From the Case Files of the OHR delivers.
The story kicks off when a man mysteriously vanishes in front of a woman named Jasmine, but unlike everyone else, she actually remembers it.
That one moment throws her straight into the hidden world of the Office of Hidden Realms, where supernatural threats are very, very real.
As Jasmine begins working alongside elite agent Sandra, the mystery only gets bigger.
A terrifying prophecy, a missing man known as the Eidolon, magical ley-lines, secret headquarters beneath Kansas City, and whispers of the ancient Serpent King all collide into one high-stakes adventure.
The story throws in Arthurian legends, witches, fae politics, and even time travel and somehow it all works.
What I loved most was the cast. Sandra is the fearless mentor everyone needs, Jasmine’s growth is fun to watch, and the side characters all bring something unique to the story.
The friendships, betrayals, and found-family vibes make the emotional moments hit just as hard as the monster battles.
Plus, the world-building is so detailed that it feels like there’s an entire supernatural society hiding in plain sight.
This book is packed with action, magic, mystery, and enough twists to keep you flipping pages.
The ending answers just enough to leave you satisfied while opening the door for an even bigger sequel.
If you’re into urban fantasy with secret agencies, mythical creatures, epic battles, and a sprinkle of Arthurian lore, this one deserves a spot on your TBR.
I’ve read this book twice already, as I was afraid I missed something the first time when I read it in earnest. Devouring it, I was enchanted by the world(s) within; spanning centuries and crisscrossing the supernatural veil with ease. I also loved the multiple points of view - not too many, yet just left with the PERFECT amount of suspense that had you cursing the end of the chapter. To say I’m looking forward to the next book is an understatement. The author has also created a website from a certain character from the book, make sure you’re checking that out too!! Then you can say you’re an OG when this turns into a Netflix special! Lastly, an unpopular opinion but I was very relieved to not have smut in a book!!
Eidolon feels like a mashup of urban fantasy, paranormal procedural, supernatural horror, and found-family adventure, but in a way that’s genuinely fun instead of overly self-aware. The setup hooked me almost immediately. A man vanishes inside a diner without any trace of magic, one witness remembers what happened while others mysteriously forget, and suddenly we’re pulled into the hidden world of the OHR, the Office of Hidden Realms. From there the novel opens wider and wider, introducing ghosts, fae, magical investigators, shapeshifters, strange prophecies, hidden archives, and a growing sense that something ancient and catastrophic is moving behind the scenes.
What worked best for me was the tone. The book balances mystery and danger with a surprisingly relaxed, conversational style that makes the world feel approachable even when the lore gets complicated. Sandra and Jasmine especially carry a lot of the early momentum. Their dynamic is one of the strongest parts of the novel because Sandra has this exhausted, sarcastic competence while Jasmine reacts to the supernatural world in ways that actually feel believable. She’s overwhelmed, curious, skeptical, and fascinated all at once. Their conversations help ground the story whenever the mythology starts expanding outward.
Nathan’s storyline adds a very different emotional layer to the book. Underneath all the monsters and magical investigations, there’s a pretty consistent thread of grief running through the novel because of Anne’s death and Nathan slowly reconnecting with abilities he thought were gone. I liked that the emotional side never completely disappears beneath the action. The supernatural elements matter, but the characters’ personal losses and fears matter too. Even some of the side characters, like Mia or Taft, feel more fleshed out than you’d expect in a book juggling this many concepts.
The worldbuilding is honestly huge. The OHR itself feels like a blend of Men in Black, The Dresden Files, Supernatural, SCP Foundation, and folklore-heavy urban fantasy. Every few chapters the reader gets introduced to something new: magical archives, latent abilities, weavers, fae bargains, edge events, ancient beings, hidden blogs, undead archivists, and supernatural politics. Normally this amount of lore would bog a book down, but Stiles usually keeps things moving by tying the exposition directly to active investigations or character interactions. The inserted guidebook sections and informational entries were also a smart choice because they help explain the setting without forcing characters into unnatural exposition dumps.
That said, the book absolutely prioritizes atmosphere, lore, and character interactions over tight plotting. There are stretches where the story feels episodic, almost like watching a supernatural TV series with monster-of-the-week energy slowly building toward a larger threat. Personally, I think that structure mostly works because the cast is enjoyable to spend time with, but readers looking for a very streamlined plot may occasionally feel like the story wanders.
I ended up really enjoying this. The novel has genuine personality, and that matters a lot in crowded urban fantasy. It feels written by someone who genuinely loves folklore, supernatural horror, conspiracy fiction, and paranormal investigation stories. More importantly, it feels like the author actually enjoys these characters. By the time the larger mythology involving the Serpent King and the Eidolon itself starts taking shape, I was invested enough that I wanted to keep following the OHR into future books.

The worldbuilding is one of the book’s strongest assets. The idea of hidden supernatural governance operating beneath an ordinary city feels fresh yet believable, and the rising tension tied to unseen forces keeps the pages turning. There’s a cinematic quality to the narrative that makes it easy to visualize, especially during moments of supernatural conflict and discovery.

A bit more “show” and less “tell” in those sections would elevate the immersion even further.
