The Immeasurable Heaven An entirely alien cast race across the multiverse in se…

Help I told my husband ONE THING about @caspargeon.bsky.social's The Immeasurable Heaven and now I'm stuck trying to explain the whole plot to my eight-year-old in the bath 😭

πŸ“¬ Through the year @scifiscavenger.bsky.social has mentioned @caspargeon.bsky.social’s β€œThe Immeasurable Heaven”.

It was hearing them chat about it together that fully tipped it onto my wishlist.

And lo, here it is, via @solarisbooks.bsky.social πŸ€—

Been hanging onto this very nice bottle that my old friend and most excellent SF author @alrobertson.bsky.social sent me a while back, but I’ve finally had some extremely good book news (which hardly ever happens) so it had better be opened. Also, those bananas need eating by the looks of things.

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.

Travelled by bus & train across the country with this today. It seems to be motion and vibration activated, even waking up and letting rip if someone passes within three feet of it. I caved at Bristol after an awkward train journey and opened up the box, worried there might be no off switch

A 3D Copy of THE IMMEASURABLE HEAVEN by Caspar Geon surrounded by white text:

β€œFearlessly creative, wildly imaginative, and wholly satisfying.” β€” Gareth L Powell

β€œWildly, explosively imaginative, The Immeasurable Heaven is a feast of a book: among the most original science fiction I've read in years.” β€”Stark Holborn

β€œThe intrigue, character, humour, plot, world building, and sheer breadth of imagination, makes The Immeasurable Heaven a truly exceptional piece of Sci-Fi. The best and most original book I’ve read in years” β€”Ed Cox, author of the Relic Guild trilogy and The Wood Bee Queen

β€œAn absolutely wild ride through a formidably original universe, filled with the bizarre and phantasmagorical.” β€”Adrian Tchaikovsky

β€œIf you're the sort of person who likes to have your brain bent in the best possible way, you really need to give this a read. This book is a wild ride, and I promise you won't regret it.” β€”Ed Ashton, author of Mickey7

β€œEscape from mundane reality to this slice of epic, bold, multiversal, sci-fi heaven.” β€”Eeleen Lee

β€œOne of the widest canvases I’ve ever read in an SFF novel... An experience like few others, in a setting completely alien to our own.” β€”Nerds of a Feather

β€œYou’re not ready for this book. The Immeasurable Heaven is a stunning ode to the weirdness living inside us that’s just waiting to be discovered, one layer at a time. To say this book is inventive is like saying the Mona Lisa is a portrait. It’s true, but it doesn’t really scratch the surface. Caspar Geon has thrown restraint out of the window. There’s more imagination in some of the sentences of this novel than there are in entire books.” – FanFiAddict

β€œA wordsmith without peer… (a) startling, unpredictable and croggling freshness of imagery and action, Geon/Toner’s new book is like the treasures of a thousand thousand phaslairs.” β€” Locus

I bought this creature as a birthday present for the child of a friend of mine, purely because when you press its tummy it farts. Brilliant. Problem is it won’t stop. I’ve been walking around town with it in a bag and it just keeps going. Went into a cafe & it got even louder. I love it, might keep

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!
