Greetings Bluesky! I’m Caspar, and my completely non-human space opera THE IMMEASURABLE HEAVEN is out July with Solaris.

I've published some fairly out-there SF under another name, but this was a very different animal that took 7 years off & on to write. Here’s a peek inside if you’re interested.

See the Solaris giveaway below to win a signed & illustrated copy of the Immeasurable Heaven. I’ve drawn as many characters and creatures from the galaxy of Yokkun’s Depth as I can fit inside, plus one or two Easter eggs for good measure..

Tune in next week for another extremely extreme worldbuilding workshop with my tree-dwelling friends - who knows what’s going to happen? I don’t.
Ca-caw! We've another week off today as the Rooks take some time to roost in their nests, but we will be back next week with Caspar Geon (Tom Toner) and the third part of his Extreme Wildcard Worldbuilding Workshop (EWWW3 - the Hunt for EWWW).

Realised that it’s 10 years to the day since my first book was published - a strange old tale set in the 147th century, featuring a giant (but very awkward) hominid protagonist. There’s a lot I’d do differently if I were writing it now, but I had such a great time coming up with so much weird stuff.

Terminator starts promisingly, being about two naked men on a quest for some trousers, but then goes off in a different direction that isn't as interesting.

An interesting thing I’ve found on my travels in Tasmania - the (thankfully) unoccupied shell of a Textile Cone, a beastie so venomous that it’s also known as the ‘cigarette snail’ (because once it’s stung you you’ve got just enough time to smoke a cigarette before you’re pushing up the daisies).

So it’s the tenth birthday of Midnight, a book that was nearly but not quite a lot of things. Happy birthday, little book. Still looking good.

Great to catch up with my old editor, Simon. ‘Tom the Not Unwelcome’ sounds like a useless but cheerful Saxon king that the chroniclers almost forgot about, and I’d be delighted to have that as my epithet
Had a very enjoyable catch-up with "the not unwelcome" (Science Fiction Encyclopaedia) @caspargeon.bsky.social yesterday. You will be hugely relieved to know that we put the entirety of science fiction publishing to rights and that everything is going to be absolutely perfect from now on. Or not.

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
