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.

The promise of the child, part 1 of the Amaranthine Spectrum

The promise of the child, part 1 of the Amaranthine Spectrum

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.

Empty shell of a venomous textile cone

Empty shell of a venomous textile cone

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 β€˜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).

The cover of Europe at Midnight, by me. It’s blue and black and features two male profiles looking left and right either side of a railway line down which a train is approaching

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.

Stone tool discovery suggests very first humans were inventors The find shows that the technology was passed down through thousands of generations.

'...tool use in (humans and human ancestors) is probably much earlier and more continuous than we thought it was.'

Great to catch up with my old editor, Simon. β€˜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

AI can help authors beat writer’s block, says Bloomsbury chief Publisher last week reported jump in revenue in academic and professional arm thanks to AI licensing deal

People who aren’t writers think writer’s block is at least as big and real a problem as I thought quicksand would be, as a child.

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

Unsolicited writing advice, no. 154:
Feed your writing daily. Feed it with fiction, non-fiction, news, games, theatre, films, art. Feed it with conversation. Feed it with experience. Feed it with curiosity. Don't expect to get anything out unless you also keep putting in.

My most recent novel is (spoiler, kind of) based on this idea. Link, as they say, in bio.

β€˜Things keep evolving into anteaters.’ Odd animals arose at least 12 separate times Findings speak to the dramatic impact ants and termites can have on mammalian evolution

Crab-like creatures are famed for having evolved five times in evolutionary history. But anteaters have evolved at least 12 times--in half the evolutionary span. Cool story by @jakebuehler.bsky.social for @science.org

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
