Caspar Geon

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.

Heading over to Comicon for today’s event with @garthnix.bsky.social and @qntm.org and the Elizabeth line has blown my mind - last time I came out this way it didn’t exist, and it took a couple of days & some complex haggling with a creature under a bridge to cross London

Reminded today of this all-timer from the early days of The Internet

As a Wealden theropod specialist, I'm pretty excited about the publication of #Invictibellatrix by @cretaceous-cass.bsky.social Morrison et al., a new theropod from the Wessex Formation of the Isle of Wight argued to be the first European megaraptoran. I wasn't involved in the research, but .... 1/n

Very nice new review, thanks @mythaxis.bsky.social ! @solarisbooks.bsky.social

Think I’ve just missed the Solaris bus*, but I’ll also be heading up to Fcon tomorrow for a couple of panels, looking forward to seeing everyone 🍻 *if it’s anything like the Vengabus, I can hopefully rejoin it in a wide range of cities

If you've been wondering what I've been up to lately, the answer is (partly)...THIS! Spotted on the Frankfurt Book Fair hotlist! Absolutely in love with this project, brought to life with my collaborators @calmdowntom.bsky.social and Alessandro Olivieri. More 👊 soon...

Malcolm was my boss for seventeen years and a very good friend for every one of those years. He scaled the heights of mainstream publishing but was always a tireless advocate for, and fan of, SFF. He was constant, gracious, very funny and a brilliant publisher. The genre owes him so much. Go well.

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

A few years ago I went to a pig sanctuary and most of the pigs were stoned from eating green acorns. This one, Wilbur, couldn’t stand up and was too big to lift, so the staff had to leave him in this bush and wait for him to sober up.

Found my first notebook with the vague ideas for the Immeasurable Heaven - to give an idea of how long these books can sometimes take, notes begin September 2018, book published July 2025 @solarisbooks.bsky.social

My art book 'Other Worlds' is available for order! Here are some purchase links :) Non-Amazon Retailers: bit.ly/4nr7Phz Amazon: amzn.to/3QYsn1s #conceptart #illustration #scifiart

Alien of the Day: A martian fox critter! Its large ears can detect sound in the thin atmosphere, while its ears and tail both help keep it warm during the Martian nights, with thin legs adapted to the low gravity. From the Picture Atlas of our Universe; a favourite book of mine as a kid.

Genre rules are only guidelines anyway! Want some Dragons in your Western? A locked boat murder mystery in your sci-fantasy? GBBO in outer space? A Necromantic bildungsroman? Searing examinations of war with bonus military Pteranodons? A literal plot device? We've got all that and more! 1/3

On the next pass, however, Helen failed to clear the mountains.
