Just sent the new book off to my publisher, and my poor, banged-up old desk is much lighter all of a sudden. Can’t say much about the new one just yet, but I’ve been working on it since 2021 and it’s unrelated to the Immeasurable Heaven. Equally weird, though, possibly even weirder…

Starting on some illustrated editions of the Immeasurable Heaven for an upcoming giveaway, probably around the middle of next month to coincide with the Australian release.

Fun evening teaching part 2 of my extreme worldbuilding workshop with @rookeryp.bsky.social, this time focussing on essentials like the Kardashev scale, Lindor chocolate balls, & why the horny robots hate the poo moon pirates. Pop along for part 3 if you fancy building an alien world from scratch.

The praise for @caspargeon.bsky.social 's THE IMMEASURABLE HEAVEN is, well, immeasurable!

Fancy a wildly imaginative scifi novel like no other with an entirely alien cast?

Here's why @garethlpowell.bsky.social @aptshadow.bsky.social & co think you would enjoy it!

A 3D Copy of THE IMMEASURABLE HEAVEN by Caspar Geon surrounded by white text:

“Fearlessly creative, wildly imaginative, and wholly satisfying.” — Gareth L Powell

“Wildly, explosively imaginative, The Immeasurable Heaven is a feast of a book: among the most original science fiction I've read in years.” —Stark Holborn

“The intrigue, character, humour, plot, world building, and sheer breadth of imagination, makes The Immeasurable Heaven a truly exceptional piece of Sci-Fi. The best and most original book I’ve read in years” —Ed Cox, author of the Relic Guild trilogy and The Wood Bee Queen

“An absolutely wild ride through a formidably original universe, filled with the bizarre and phantasmagorical.” —Adrian Tchaikovsky

“If you're the sort of person who likes to have your brain bent in the best possible way, you really need to give this a read. This book is a wild ride, and I promise you won't regret it.” —Ed Ashton, author of Mickey7

“Escape from mundane reality to this slice of epic, bold, multiversal, sci-fi heaven.” —Eeleen Lee

“One of the widest canvases I’ve ever read in an SFF novel... An experience like few others, in a setting completely alien to our own.” —Nerds of a Feather

“You’re not ready for this book. The Immeasurable Heaven is a stunning ode to the weirdness living inside us that’s just waiting to be discovered, one layer at a time. To say this book is inventive is like saying the Mona Lisa is a portrait. It’s true, but it doesn’t really scratch the surface. Caspar Geon has thrown restraint out of the window. There’s more imagination in some of the sentences of this novel than there are in entire books.” – FanFiAddict

“A wordsmith without peer… (a) startling, unpredictable and croggling freshness of imagery and action, Geon/Toner’s new book is like the treasures of a thousand thousand phaslairs.” — Locus

Bought a lovely 18th century print at Bath market this morning of something that I don’t think exists yet, chilling out in the ruins of civilisation millions of years hence

This repost is, theoretically, against the law as I haven't read it yet. But, being 2/3rds of the way through Tom/Caspar's Amaranthine Trilogy, I can confidently deduce that this book will be utterly bloody marvellous.

Due to a warehouse problem around launch time, the Immeasurable Heaven won’t be stocked in any Waterstones for the foreseeable future.

I’ve compiled a headache-inducing pile of nice blurbs and would be so grateful if anyone who enjoyed my weird non-human book could reshare.

Thank you!

huge dragon (only the head visible) resting in a body of water in a forest. Lots of vines and tree branches dangling down, a stream running over its head and a great white egret taking off from the water next to it. a mermaid with a pink tail resting on a rock and leaning back on her hands as her tail comes out of the water. In the background is a lagoon and some cliffs and further back the hint of a waterfall a precarious tall hill with a wizard's house sitting on top of it with a wisp of smoke coming out of the chimney. It is dusk and all the windows are yellow with the light from inside. a large winged blue dragon prepares to land on a nest with two baby blue dragons waiting in the nest for their dinner.

Apparently the Immeasurable Heaven comes out in Australia next month (fair dinkum), so more random sketches of the inhabitants of Yokkun’s Depth incoming daily to celebrate.

Here’s a bellower (key for a tongue), a tootlebeast & its marvellous sled.

New #review - For the Road by @starkholborn.bsky.social. Very grateful to the author for a copy of this gritty, myth-haunted weird Western fantasy, a young man faces truths and consequences. An absorbing read. bluebookballoon.blogspot.com/2025/09/revi...
Cover of book “For the Road” by Stark Holborn. A right hand held up with a heart in its palm. Wrapped around it, an infinity of looped railway track.

Working on my most frustrating book yet. Thought I’d finished after 3 drafts in 2023, then took it back to the drawing board with a big rewrite in 2024. Now realise I haven’t understood it at all. In 2026 I’ll see that I’ve got it wrong again, and in 2027 I’ll realise it was correct the first time.

Found a sketch I must have done years ago of Scallywag the Cethegrande (from my third book, the Tropic of Eternity) in his fancy translucent armour. I’d forgotten how weird that book was.

Another fun Extreme Wildcard Worldbuilding Workshop last night with the @rookeryp.bsky.social , taught from my boiling hot spare room. Some good notes, including ‘space sepsis’, ‘accidentally horny’, and (my personal favourite) ‘what happens if it farts’.

This was a hoot! @tomtoner.bsky.social was great as always and the chat brought tons of brilliant ideas to bear. It's available to watch now, check it out. We're planning a part two, and I'm also thinking about how to adapt it for school...
