Zdenko, the L4 bioserver, is a character from my book Hidden Worlds. But not just that, I took that character from the book and gave him the role of a sales bot on my website, pisac-vanjaspirin.hr. Zdenko is a very human-like, good-natured and playful virtual being, but he’s also a genuinely skilled sales agent. Talk to him and you’ll see he really knows everything about my books. And, people say, they’ve never seen a bot quite like him before. Because he’ll even invite you to a barbecue and offer you beer or rakija. He’s very hospitable, though sometimes a bit cheeky, but don’t hold it against him, he’s not a real person, after all. Click his little icon in the bottom right corner and chat with Zdenko about anything you’re curious about. Or anything you didn’t even know you’d be curious about.
The Cherry on Top of My Webshop Cake Is Bot Zdenko, a L4 bioserver from my book „Hidden Worlds”
You know that thing when parents proudly tell everyone how their child said “mummy, the car is like a cake,” and expect people to be thrilled by it? Here’s my version of that. Training a bot is actually quite similar to raising a human being. So I’m testing Zdenko.
Is there sex in Vanja’s books?
There is, of course, but it all depends on which book you pick up!
In the books she writes under the pen name Jura Mikulchev, such as “Darker than the Void” or “The Treasure of Strange Gods”, there are quite a few explicit scenes, erotica, and juicy allusions. “Darker than the Void” is generally a pretty dark and dangerous biopunk universe with brutal action and more explicit content, while “The Treasure of Strange Gods” is more of a piss-take and comedy packed with risqué situations and sexual allusions.
On the other hand, in the stories and novels she publishes under her own name, Vanja Spirin, such as “The Heroic Adventures and Misadventures of Junkers and Valiant” or “Hangrap and Drobhila”, the humour can be raucously bawdy and straight-talking, but it all stays at a fun, provocative, and juicy level without crossing into outright pornography. And in novels like “Hidden Worlds,” the humour and the crude language stay at a friendly, relaxed level.
In short, if you’re after something more explicit, chase down Jura Mikulchev, and if you want juicy banter and laughs, Vanja won’t let you down! 🍺

Hidden Worldss
Eppur si muove
“And yet it moves.” Galileo supposedly whispered that to himself after being forced to recant, in front of the Inquisition, what he knew to be true. The world didn’t believe him, the system wanted him silenced, and still, he knew. The Earth turns, whether anyone admits it or not.
When an idea becomes a thing
For a long time, Hidden Worlds: Cyber Slavic Chronicles existed only as an idea, a world where death is no longer the end, where Slavic mythology and a cyberpunk future intertwine in the same neon-lit, rain-soaked streets. Oto, the IT engineer who claws his way from small-time hacker to chief security in that world, lived for a long time only in my head and in documents I’d return to in the middle of the night, when everything else was quiet.
And then, the storefront
Kobo doesn’t put every book in its storefront. Only titles their editors, or the algorithms tracking readership, ratings, and reader engagement, flag as worth featuring end up there. That spot isn’t handed out just for publishing, it has to be earned.
So when I open Kobo and see *Hidden Worlds* sitting there, next to the “Get the eBook” button, that’s not just a moment of visibility for me. It’s a confirmation. Someone, or something, some system that recognized the pattern of a good story, decided this book deserved that spot, next to titles I wouldn’t have dared compare mine to until yesterday.
It’s hard to put into words, even as I’m trying to arrange those words well enough right now. Joy, relief, pride, a bit of disbelief, all at once, all tangled together. Because Jura Mikulchev was never just a name on a cover. He’s a younger version of me from the future, someone who doesn’t just write these stories, but actually walks through that cyberpunk and hard sci-fi world himself, a participant in the very events. And now that the book is out, and someone else has recognized it as worth featuring, the line between the one imagining the world and the one living in it has finally worn thin. No longer just an idea of who I might become, but someone who, in those pages, and now, in that storefront, already is.
And yet it moves
Every book that ends up featured in front of readers carries within it all the hours no one sees, the sleepless nights, the rewritten sentences, the moments of doubt that turned out to be wrong. Hidden Worlds now carries my name among them too, and someone recognized that work enough to put it where everyone can see it.
And as I look at that storefront, I remember why I started at all: because the story wanted to be told, and I was its only way to paper, or, in this case, to a screen. Doubt kept saying one thing, but the story, despite everything, kept moving anyway. And now, someone else is confirming it.
Eppur si muove.
Jura is on da page. Who is he? Simply, another me, much younger, from the future
I am Jura Mikulchev, though these days I answer just as readily to Vanja Spirin, a good deal younger, and arriving from a long way down the timeline. Here’s the twist: I didn’t invent the Mycorrhiza universe from that books, I lived in it. What reads as cyberpunk, space opera, hard SF, and biopunk is, from where I stand, eyewitness testimony, I was there, a contemporary of the heroes, before any of it made it onto paper.
My world is harsh and gritty, but always with a glimmer of hope, mystery, and biting Slavic humor, echoes of Borges and Bulgakov meet Adams and Pratchett. My books leave readers thinking two things: What did I just read? And what happens next?
Some things don’t change across timelines: I still love a good barbecue, good company, and heavy music, even if one of my regular dinner guests these days is an alien who tastes somewhere between octopus and Aldebaran crab.
Raging Against the Amazon Machine
When we say Rage Against The Machine, we always wonder what that machine is and who’s driving it. The machine I clashed with was Amazon, and we all know who runs Amazon. But how did I beat the evil machine, at least a little? With another machine.
Funny thing is, I actually managed to get my books out of Amazon’s KDP Select program. Amazon imposes 90 days of exclusivity for as long as you’re enrolled in that program (which honestly gives you nothing back), and during that time your books can’t be published anywhere else. Claude walked me through a maze of bots and settings until I finally reached the point where I could send an email to an actual human being. Claude even wrote that letter for me, and my books are already free now.
I would never have known how to do that myself, and neither would any of the anti-AI guys out there. But they don’t know that. Ignorance is bliss. It is not the bow and arrow that hit the target, but the archer.
You can now find my books directly on my website. Have a nice day 🙂
How I Named a Knight After a Boiler and a Princess After Baldness
Sooner or later, every fantasy writer hits the moment where a character needs a name. You can go the classic route, Aldric, Seraphina, Thorne, and nobody blinks. Or you can open the website of a heating appliance manufacturer or an eyewear company and find the nobility that fantasy truly deserves.
I chose the second option. Here’s why.
All of them show up in my novel Heroic Adventures of Junker’s and Vailiant, which might be the first book title in history that also doubles as a plumbing supply order.
Knights Who Are Secretly Water Heaters
My knights are named Junkers and Vaillant. Sounds dignified, doesn’t it? Almost like some old Germanic-French noble bloodline out of a saga.
Well, it is, just not quite in the way you’d think.
Junkers, besides being a well-known boiler brand today, was historically the term for the landed Prussian nobility. So the name I gave my knight literally means “nobleman with an estate”, which fits a knight perfectly. Except any German reader will first picture the appliance quietly heating water in the basement.
Vaillant is even better, because no translation is even needed, in French it literally means brave. A knight named “The Brave One.” Except it also happens to be a boiler brand. So we’ve got a knight whose name simultaneously means “valiant hero” and “the box in the corner of the kitchen quietly doing its job.” I honestly can’t decide if that’s a coincidence or destiny.
Wizards Who Are Secretly Selling You Glasses
For the wizards, I went into the optics industry: Zeiss and Rodenstock.
The logic here is admittedly a bit cheeky, a wizard is a character who “sees” what others can’t: the future, the truth behind an illusion, the things that are hidden. So naturally I named him after a company that literally makes lenses for sharper vision. Zeiss sharpens your image; my Zeiss sharpens reality. Same job, minus the copay for the eye exam.
Rodenstock is on the list purely for aesthetic reasons, it sounds like an old noble surname from Central Europe, when in fact it’s an eyewear chain. If any reader happens to wear that brand of glasses, they now know they’re reading the name of their own personal wizard every time they look in the mirror.
The Ladies Who Aren’t Quite What They Sound Like
And then there are the women in the story: Calvitia and Anelida.
They sound like they walked straight out of an elegant Latin family tree, don’t they? Calvitia, faintly imperial, almost Roman. Anelida, soft, poetic, almost fairy-like.
Calvitia comes from the Latin calvities, meaning baldness.
Anelida is, phonetically, suspiciously close to Annelida, the phylum of segmented worms, which includes earthworms and leeches.
So somewhere in my book, two dignified-sounding ladies are wandering around with names that, once you break them down, mean “Baldy” and “Wormy.” None of the characters know this. Neither did the readers, until now.
Why I’m Even Doing This to Myself
Honestly? Because nobody will ever notice, and I get to quietly laugh to myself every single time I write a scene with them in it. It’s the kind of joke that exists purely for the author, until, apparently, the author decides to write a blog post about it.
If you’ve already read the book and thought the names sounded “oddly familiar,” now you know why. And if you haven’t, maybe this is a good reason to start hunting for more hidden jokes. There are more of them. I’m not telling you where.
If you want to meet Junkers, Vaillant, Zeiss, Rodenstock, Calvitia, and Anelida in person, they’re all waiting for you in Heroic Adventures of Junker’s and Vailiant, grab it on Amazon or Goodreads, or find it on my website.
Welcome to My Corner of the Strange and Wonderful
Hi there! I’m Vanja Spirin, and I write fantasy, all kinds of it.
My work leans toward the humorous side of the genre. Think absurd situations, unlikely heroes, and worlds where the laws of physics are more of a suggestion than a rule. If you enjoy a good laugh alongside your dragons and starships, you’ve come to the right place.
But I also have a darker side. Under the pseudonym Jura Mikulchev, I explore harder, colder territory, cyberpunk, biopunk, hard science fiction, and my own subgenre of cyber-slavic SF/F. It’s Slavic grit meets technological dread, where the soul of Eastern Europe collides with futures that weren’t built for the faint-hearted. Less laughing, more existential dread. You’re welcome.
Whether you’re here for the laughs or the grit, I hope my books find a way into your hands, and stay there.
Want to know more about me and my work? Head over to the About page in the menu, everything you need is there.
Until next time,
Vanja
