I’ve never done an eligibility post before because my books aren’t well known, but this little monster’s been unexpectedly nominated for a couple of awards now (& took a huge amount of work to bring to life) so any votes for upcoming stuff would be very much appreciated 🍻

Amazing article, 2 thoughts
1) absolute cosmic horror fuel (as per Ethan’s note)
2) they gave it to mice. Did the mice see mouse-sized people or even tinier mice?

Immeasurable Heaven is 30% off on Amazon UK - according to my (possibly wrong) calculations that's 45 pages of alien characters, ice moon battles, stolen planets, fungal spaceships & dimension-hopping sorcerers per pound. There's also a very amusing incident with a kebab

Against a blue background, tiled book covers:

THREE EIGHT ONE and THE MISHEARD WORLD by Aliya Whiteley
RAKESFALL and THE SAINT OF BRIGHT DOORS by Vajra Chandrasekera
THE SALT ORACLE by Lorraine Wilson
THE MOUNTAIN CROWN by Karin Lowachee
THE DEATH I GAVE HIM by Em X. Liu
SAINT DEATH'S DAUGHTER by C. S. E. Cooney
THE SIEGE OF BURNING GRASS by Premee Mohamed
THE IMMEASURABLE HEAVEN by Caspar Geon

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!

Maps and Legends: The Spectacular Cartography of Ursula K. Le Guin - Library of America Mapmaking lay at the heart of Ursula K. Le Guin’s worldbuilding. An able illustrator whose subjects ranged from realist watercolors to cartoon cats, the author of such SFF classics as The Left Hand of...

Not just a novelist, @ursulakleguin.com was also a cartographer. Her fictional geographies were on display this fall at London’s Architectural Association Gallery, and a companion book on Silver Press sheds new light on her peerless world-building.

On the left, an old carry case with a cursive writing label. On the right, a glossy black obsidian mirror.

It's my birthday!
As such, I'd like you to consider leaving a book review or preordering one - doesn't have to be one of mine. It really helps authors out.
Also, here is a photo of John Dee's obsidian scrying mirror, which I found cool.
