Found a bunch of sketches I did of the 147th century post-human beasties from my first trilogy, the Amaranthine Spectrum. Had so much fun coming up with these offshoots of humanity and imagining their filthy, chaotic worlds - would love to write another book about them one day

Desk covered in stuff
Just sent the new book off to my publisher, and my poor, banged-up old desk is much lighter all of a sudden. Canโt say much about the new one just yet, but Iโve been working on it since 2021 and itโs unrelated to the Immeasurable Heaven. Equally weird, though, possibly even weirderโฆ

A 3D Copy of THE IMMEASURABLE HEAVEN by Caspar Geon surrounded by white text: โFearlessly creative, wildly imaginative, and wholly satisfying.โ โ Gareth L Powell โWildly, explosively imaginative, The Immeasurable Heaven is a feast of a book: among the most original science fiction I've read in years.โ โStark Holborn โThe 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 Iโve read in yearsโ โEd Cox, author of the Relic Guild trilogy and The Wood Bee Queen โAn absolutely wild ride through a formidably original universe, filled with the bizarre and phantasmagorical.โ โAdrian Tchaikovsky โIf 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.โ โEd Ashton, author of Mickey7 โEscape from mundane reality to this slice of epic, bold, multiversal, sci-fi heaven.โ โEeleen Lee โOne of the widest canvases Iโve ever read in an SFF novel... An experience like few others, in a setting completely alien to our own.โ โNerds of a Feather โYouโre not ready for this book. The Immeasurable Heaven is a stunning ode to the weirdness living inside us thatโs 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. Itโs true, but it doesnโt really scratch the surface. Caspar Geon has thrown restraint out of the window. Thereโs more imagination in some of the sentences of this novel than there are in entire books.โ โ FanFiAddict โA wordsmith without peerโฆ (a) startling, unpredictable and croggling freshness of imagery and action, Geon/Tonerโs new book is like the treasures of a thousand thousand phaslairs.โ โ Locus
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!

13.09.2025 09:23 โ ๐ 4 ๐ 1 ๐ฌ 0 ๐ 0This 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.
12.09.2025 15:01 โ ๐ 2 ๐ 2 ๐ฌ 1 ๐ 0Due to a warehouse problem around launch time, the Immeasurable Heaven wonโt be stocked in any Waterstones for the foreseeable future. 
Iโve 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.
It's my birthday!! I'm 49 - how did that happen? I would LOVE it if you could share or follow my art for my birthday, that would be a brilliant gift! Thank you everyone who follows and comments, it is such a great place here! 49 feels ace btw. #artshare #birthday #watercolour

Apparently the Immeasurable Heaven comes out in Australia next month (fair dinkum), so more random sketches of the inhabitants of Yokkunโs Depth incoming daily to celebrate.
Hereโs a bellower (key for a tongue), a tootlebeast & its marvellous sled.

Working on my most frustrating book yet. Thought Iโd finished after 3 drafts in 2023, then took it back to the drawing board with a big rewrite in 2024. Now realise I havenโt understood it at all. In 2026 Iโll see that Iโve got it wrong again, and in 2027 Iโll realise it was correct the first time.
