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).

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

I've decided that whilst critical success is lovely, I'd like to sell some books.

If you liked EXTREMOPHILE, recommend it to a pal! (If your pal is fucking COOL and not a narc)

Eco-terrorism biohacking body horror, smart shit with dumb characters. Your new favourite book
'A visceral, doesn't-give-a-damn biopunk thriller that treats the "punk" part of that subgenre not as mere window-dressing but as an antifascist shriek... vital and urgent SF that reaches places realist writing never could' ― @interzone.press

If you like cool shit get this 🕶️

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.

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!

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.
