Great crowd for my Extremely Extreme Wildcard Worldbuilding Workshop (EEWWW) today at @jerichowriters.bsky.social. We learnt some very useful information today, including that ‘everything’s hairy’, and ‘music vibrates the pus’. Most illuminating.

There may (or may not) be tickets left for my Extremely Extreme Wild Card Worldbuilding Workshop at the London Festival of Writing this weekend. Not a particularly helpful message, but if you’d like to shout things at me in a small room while I note them down on a whiteboard, pop along.

Who is this Caspar person, anyway?

Posted already on Instagram, but I can now reveal that Caspar Geon is the interdimensional pen name of a bizarre fellow named Tom Toner, the author of the far-future space opera series the Amaranthine Spectrum.

Such a nice launch yesterday for my friend Mona’s new book Growing, at the very lovely @ifordmanor.bsky.social - if your walking onions keep scampering away, this one’s for you

Made the mistake of looking through Goodreads and found possibly my favourite review of my first book - ‘I… kind of speed-read the whole thing to distract myself from the looming prospect of death’

Had a lovely time in Waterstones Piccadilly yesterday writing my name on things that already have my name on them in multiple places
