From Wyverns to Whispers: How J. Cronshaw Moved from Fantasy to Thriller

Fantasy author Jon Cronshaw shares how writing The Nanny’s Secret—his first domestic thriller—reignited his creativity after completing The Ravenglass Chronicles. Discover how his new pen name, J. Cronshaw, opened a new chapter in his storytelling career.

If you’ve been following my work for a while, you probably know me for wyverns, assassins, and dark fantasy worlds.

I’ve been publishing fantasy and speculative fiction since 2016, and I’ve been a full-time author since 2018.

Most of my readers found me through The Ravenglass Chronicles—a long-running epic about magic, destiny, and rebellion that spanned half-a-million words. It was an intense creative journey, and by the time I finished it, I needed to catch my breath.

In 2022, I decided to write something completely different. No magic. No kingdoms. No wyverns. Just people. Ordinary lives under extraordinary pressure. It started as a palate cleanser, a little side project to clear my head before diving into my next fantasy series. That story became The Nanny’s Secret.

At the time, I didn’t think I’d ever publish it. It didn’t fit with my other books. I love reading psychological thrillers, but I saw them as something separate from what I wrote. I wasn’t keen on setting up a new pen name or building a whole second author brand. So I set the manuscript aside and got on with other things.

But the idea of writing thrillers stuck with me.

The stories kept coming—small-town secrets, lies, betrayals, and the dark undercurrents that run beneath everyday life. Before long, I’d written a second thriller, then a third. Now, I’ve written eight and I’m working on my ninth.

When I showed them to a friend who writes thrillers, he told me I was mad not to publish them. I told him I didn’t want to annoy my regular eaders, and I didn’t want the stress of juggling two identities. He gave me a simple solution: drop my first name.

So “Jon Cronshaw” became “J. Cronshaw.”

Same writer. Different shelf.

That small change made everything click.

I’ve since built a new website, newsletter, and social media presence for J. Cronshaw—the domestic thriller author.

I’ll admit, I was reluctant at first. Starting over from scratch after years of building my fantasy world felt strange. But once I began, I rediscovered something I hadn’t felt in a long time: the spark of building something brand new.

These domestic thrillers are grounded in real life. They draw on my years as a court reporter, on real places near where I live—Morecambe, Heysham, Lancaster.

The stories are intimate and claustrophobic, the kind of tension that doesn’t need magic to feel dangerous. And in a way, writing them has made me a better fantasy author too. They’ve sharpened my sense of pacing, dialogue, and emotional realism.

I’m still writing fantasy—always will.

The Ravenglass Legends series is continuing, and there are more stories from that world on the way. But writing thrillers under J. Cronshaw has reminded me how much I love storytelling in all its forms. It’s a different kind of worldbuilding—one built from truth, not myth.

So if you ever fancy reading something a little different from me—something without wyverns, but still full of secrets and twists—you can download your free copy of The Lodger HERE to give you a flavour of what I’ve been doing.

And if you’d like to hear more about what I’m working on—both fantasy and thriller—you can listen to my weekly Author Diary podcast. I’ve been recording every week since 2017 and haven’t missed an episode.

It’s been a strange journey from wyverns to whispers, but I’m glad I took it. Because sometimes, stepping outside your world is the best way to remember why you built it in the first place.

🌲 Mini-Break, Nautical Fantasy Rewrite & Staying Prolific | Author Diary – August 15, 2025 🐚🚀

This week, I took a mini-break to Chester, enjoying peaceful walks in Delamere Forest, the stunning Chester Cathedral, and strolling the historic city walls—a great way to reset.

Creatively, I’ve been working on Hunters, my wacky Space Western originally written as a Patreon side project. I’m now rewriting it as a nautical fantasy set in the Ravenglass Universe, and it’s been a fun challenge adapting the tone and setting while keeping the spirit of the original.

I also reflect on my prolific writing strategy—following my energy and excitement rather than rigid plans, which keeps things creatively fulfilling.

Elsewhere, Trial of Thieves has now been submitted to ACX, so the Audible edition should be available soon.

The paperbacks for the Punks Versus Zombies trilogy are now ready, and audiobook production is underway.

Draft Complete: The Silent Watcher & New Sentinel Story Begun | Author Diary, August 1, 2025

I’ve completed The Silent Watcher draft and sent it to alpha readers. Also starting my gritty Sentinel novel in the Ravenglass Guardians series.

This week, I finished my draft of The Silent Watcher—the first completed novel in my Ravenglass Guardians series—and sent it to alpha readers for early feedback.

I’ve also begun the next standalone in the series, centred on the Sentinel faction.

While The Silent Watcher is a slow-burn psychological thriller, the Sentinel novel is shaping up to be a gritty military fantasy—both firmly in nobledark territory.

On a personal note, my son is off to Denmark to compete in the Youth Games for karate.

🛡️ 75% Draft Progress & Next Guardian Story Outlined | Author Diary – July 25, 2025 📚✨

This week, I reached 75% of my Watcher draft in the Ravenglass Guardians series and began outlining the next standalone novel, which will follow the Guardians’ Sentinel faction.

This week, I’ve made solid progress on my Watcher story in the Ravenglass Guardians series, hitting the 75% mark in my draft.

 If everything continues smoothly, I should have a complete draft by the end of next week.

I’ve also been outlining the next standalone novel, which will follow a character from the Guardians’ Sentinel faction. Each book in this series will explore a different path of the Guardians, with all seven forming a powerful nobledark saga.

👁️ Midpoint Milestone in Ravenglass Guardians | Author Diary – July 18, 2025 📚✨

This week, I reached the midpoint of my first Ravenglass Guardians novel, a nobledark fantasy with political thriller vibes. I’m planning seven 60k-word standalones, written before Patreon release.

This week, I hit the mid-point in drafting my first Ravenglass Guardians novel, focusing on the Watchers faction. It’s a nobledark fantasy with strong political thriller elements.

Since each of the seven planned books will be standalone, this may not be the first released—but my goal is to write the full series before launching it on Patreon.

I’m aiming for 60k-word novels (like my Guild of Assassins books), which allows me to draft a solid book in about four weeks, writing 3,000 words per weekday—a pace I’ve kept up for years. It’s a challenge, but one I’m excited to push through!

👑 New Series Begins: Ravenglass Guardians | Author Diary, July 11, 2025 📚✨

This week, I began work on my new seven-book nobledark fantasy series about the Guardians in the Ravenglass Universe, reaching 25% of Book 1. Plus, I share why I’m focusing on shorter, 60k-word novels.

This week, I’ve dived into my new series set in the Ravenglass Universe, focusing on the Guardians—a seven-novel, nobledark fantasy exploring the different paths within the order. I’ve written the first six chapters of Book 1, putting me at 25% of the draft already.

I also reflect on my shift toward writing more 60,000-word novels, similar in length to the Guild of Assassins books. This feels like the sweet spot for the kinds of focused, intense stories I want to tell going forward. Exciting times ahead!

Meet the King of Nobledark: Jon Cronshaw’s Author Manifesto

Jon Cronshaw declares himself the King of Nobledark—because someone had to. In this post, he explains what nobledark fantasy is, why it matters, and how a ravenglass sword and some highly trained wyverns keep the crown in place.

I didn’t mean to become the King of Nobledark.

Truly.

I was just minding my own business, poking around the edges of grimdark, whispering sweet nothings to hope, when I stumbled upon a dusty old crown lying in a forgotten corner of the fantasy genre.

No one was wearing it.

No one was even looking at it.

So, I picked it up, gave it a polish, and popped it on my head.

It fits rather well.

Naturally, I assumed someone would try to stop me. Perhaps a grimdark usurper, still drunk on blood and betrayal, lurching from the shadows, broadsword in hand, quoting Nietzsche and snarling about nihilism.

But alas, no.

Apparently, claiming the crown of Nobledark—that little corner of fantasy where honour still breathes (barely), where sacrifice means something, and where good people try to stay good in worlds that want them broken—isn’t high on anyone’s to-do list.

So here I am.

Jon Cronshaw. The King of Nobledark.

Now, I realise some of my fellow authors might feel tempted. You may think, “That crown would look rather fetching atop my morally complex, world-weary protagonist, actually.”

And I respect that.

But before you mount your literary siege engines, a word of warning: I’ve got wyverns. Highly trained ones. They don’t breathe fire—they just watch. Constantly. Silently. Judgementally. And if that doesn’t unsettle you, it really should.

I also carry a Ravenglass blade, forged with my own blood and tears. Beautiful, yes—but with the rather unfortunate side effect of burning its victims from the inside out. You won’t notice at first. You’ll think you’re fine. And then the screaming starts.

So if you, too, write stories where the world is cruel, but your characters dare to care anyway… then by all means, take up the mantle. Write nobledark. Spread the word. Let readers know that fantasy doesn’t have to choose between despair and delusion.

But the title?

That’s mine.

Unless, of course, you think you can take it.

(You can’t.)

Long live nobledark.
Long live the King.
