Gideon the Ninth meets Moby-Dick in USA Today bestselling author Alexis Hall's thrilling SF debut, Hell's Heart!

They are monsters, legends, gods.



They are our prey.

Earth is dead. Which leaves us stuck living in atmospheric domes on planets that will kill us if we blink wrong, or run out of fuel. And by “fuel” I mean “the cerebrospinal fluid of gargantuan, quasi-psychic space monsters”.

I joined the hunt hoping to get paid and maybe laid, but mostly paid. Instead, I followed a captain chasing abominations in the skies of Jupiter.

We battled the Möbius Beast itself, there in the red eye of the world.

Spoiler: we lost.

Praise for this book

Praise for Hell's Heart:

"Wow."—John Scalzi

"Hell's Heart is a startling, ferocious love letter to all the rawest emotions the human body can produce. Hall is a master of voice and scale, and this relentlessly gripping ode to the splendors and miseries of existence is no exception. I can't think of anyone else who could successfully pull off Moby Dick meets Treasure Planet by way of Fleabag -- an unbelievable accomplishment from a tremendous author."--Sarah Gailey, USA Today bestselling author of Spread Me and Just Like Home

"Fey, funny, and extremely metal."--Malka Older, author of The Mimicking of Known Successes

“A towering love song to both Melville and Joan D. Vinge, a marvelous, intricate, heart-shattering romp.”--Lilith Saintcrow, author of the Dante Valentine series

"Hell's Heart goes like gangbusters and is entirely unhinged. I'll follow Alexis Hall anywhere."--Kelly Robson, author of High Times in the Low Parliament

"Call me fangirl! This is Hall’s best, weirdest, and most snarkily delightful book yet. Whether you like even-more-queer Moby Dick retellings, space whales, disaster bi drama, Jovian gaslamp science fiction, razor-sharp satire of capitalist theology, Locked-Tomb-style obscure jokes, Cthulhu cultist crew members, thematically-important infodumps about xenobiology – or better yet all of those things tied together in intricate perfection – this will be your jam."—Ruthanna Emrys, author of A Half-Built Garden

"Unlike Melville’s Ishmael, Hall’s protagonist has sexual relationships that are textual rather than subtextual and also pretty hot. The worldbuilding is strong and—as is the case in the most resonant science fiction—disturbingly plausible... a good old-fashioned space yarn." – Kirkus



Praise for Alexis Hall:

"Hall is a dizzyingly talented writer, one likely to spur envy in anyone who's ever picked up a pen."—Entertainment Weekly on Boyfriend Material

"Simply the best writer I've come across in years."—Laura Kinsale, New York Times bestselling author

"Absolutely delightful, like a chocolate box, full of unexpected and brilliant references, sparklingly witty.”—Genevieve Cogman, author of The Invisible Library on The Affair of the Mysterious Letter

“An extended romp through a wild range of alternate universes with a bizarre cast of characters. Don't miss this fun, queer, clever intrigue!”—Malka Older, author of The Mimicking of Known Successes

"I haven’t been so enchanted and delighted by a book in years... the most perfect blend of gentle humour, wild creativity and love."—Emma Newman, author of Atlas Alone

"Extraordinarily imaginative. This is the most fun I've had between two covers in a while!"—Lara Elena Donnelly, author of Amberlough

"Full of adventure, chaos, magic, and lust, this will enthrall Hall’s fans and new readers alike."—Publishers Weekly, starred review, on Mortal Follies

"Utterly enchanting"—Publishers Weekly, starred review, on Confounding Oaths

"Thoroughly queer and extraordinary."—Kirkus, starred review, on Something Extraordinary

"Hall has a gift for humor but is also skilled at composing passages that evoke the deepest emotions, whether the ache of long-denied love, crushing grief or the relief and soulful joy of being accepted and adored as one's most authentic self.”—Library Journal, starred review, on A Lady For a Duke

“Hall has hit it out of the park with this emotionally resonant, character-driven Regency romance... stellar.”—Bookpage, starred review, on A Lady for a Duke

"Hall is a consistently beautiful writer."—Kirkus, starred review, on A Lady for a Duke

"The characters are charmingly flawed, with enough chemistry to see them through some serious ups and downs... full of poetry and honesty."—Publishers Weekly, starred review, on For Real




About the AuthorSome years ago—never mind how long precisely—having little or no money in their purse, and nothing particular to interest them on shore, Alexis Hall thought they would sail about a little and see the watery part of the world. Unfortunately the boat they were in sank with all hands, and they were rescued only by a passing whaler. They have since become a novelist.
