Dark stories where hope bleeds, but never dies.
Wyverns bonded by blood. A black material that warps light and refuses to break. Empires that rise, conquer, peak, and crumble across a thousand years of history.
I’m Jon Cronshaw—author of the Ravenglass Universe and self-appointed King of Nobledark. I write epic fantasy for readers who want their heroes flawed, their magic costly, and their empires morally complicated.
No spice. Deep characters. Complex stories that earn their weight. If you’re here for the world and the people inside it, you’re in the right place.

LATEST RELEASE
Silent Watcher (A Ravenglass Guardians novel)
“So very good!”
A dead agent. A silent town. A conspiracy written in her own hand.
Watcher Anselma Versen arrives in Halborg under a false name to investigate a colleague’s death.
The official report says accident.
The evidence says murder.
Witnesses repeat the same rehearsed answers. Records vanish overnight. Then Anselma discovers reports bearing her own signature, authorising operations she never witnessed and dated to days she cannot remember.
Someone knew she was coming. Someone has already decided what she will find.
And the last Watcher who asked these questions is already dead.
Silent Watcher is a standalone fantasy spy thriller about secrets, deception, surveillance and institutional betrayal. It’s also the first book in Ravenglass Guardians, a new series of seven standalone novels set a century after Ravenglass Legends.
Available now in Kindle, paperback and audiobook, narrated by Claire Aston.
Enter Halborg. Question everything.
STEP INSIDE THE RAVENGLASS UNIVERSE
A thousand years. Four eras. One unfolding history.
The Ravenglass Universe spans royal sisters and bonded wyverns in the First Kingdom, brutal conquest and rebellion in the Expansion, prophecy and divine power at the High Empire’s peak, and shadow warfare through the slow Retraction that ends it all.
Every series stands alone. Read in any order. Or follow them across centuries and watch a civilisation rise and fall — with a black wyvern named Witz drifting through the wreckage, present at every turning point, claimed by no one.

LISTEN TO THE LATEST AUTHOR DIARYThe campfire between books.
Every week, I sit down and talk about what I’m writing, what I’m reading, what’s gone wrong this week, and what I’m doing about it. New books taking shape. Old ones getting their second pass. The occasional detour into wrestling, running, or whatever I’m currently obsessed with.
It’s the Author Diary—part writing journal, part workshop notes, part me thinking out loud about the Ravenglass Universe and what’s coming next. No script. No production team. Just a writer with a microphone, talking to whoever’s listening.
If you’ve ever wanted to know what the inside of a working novelist’s week actually looks like—start here. New episode every week.
