High Vaultage turns Victorian invention into a citywide tangle of impossible crimes, private detection, and absurd machinery.
High Vaultage
Sci-Fi · Galactic Empire · Steampunk
Our take
High Vaultage turns Victorian invention into a citywide tangle of impossible crimes, private detection, and absurd machinery. In Even Greater London, Archibald Fleet and Clara Entwhistle run a barely respected detective agency until a kidnapping case pulls them into a mystery linked to baffling bank robberies and the city’s strange infrastructure. This steampunk mystery blends cozy investigation, alternate history, and comic science fiction with a satirical edge.

About the book
From the creators of the acclaimed audio drama podcast Victoriocity comes a cozy scifi mystery set in the chaotic metropolis of Even Greater London - unmissable for fans of Ben Aaronovitch's Rivers of London series and Terry Pratchett's Discworld.
EVEN GREATER LONDON, 1887: a vast, uninterrupted urban plane encompassing the entire lower half of England and, for complex reasons, only the upper third of the Isle of Wight... The immense Tower casts electricity across the sky itself, powering the mind-boggling mechanisms of the city below; the notorious engineer-army swarms through its very veins, building, demolishing, and rebuilding whatever they see fit; and - at the heart of it all - sits the country's first ever private detective agency.
Archibald Fleet and Clara Entwhistle hoped things would pick up quickly for their new enterprise. No one is taking them seriously, but their break will come soon. Definitely... Probably.
Meanwhile, police are baffled by a series of impossible bank robberies, their resources wholly absorbed by the case. Which means that when a woman witnesses a kidnapping, Fleet-Entwhistle Private Investigations is the only place she can turn for help. Luckily they're more than happy to oblige.
But what's the motive behind the kidnap? As Clara and Fleet investigate, they find more than they could ever have imagined...

Memory becomes a survival problem when a girl wakes with violent hunger and no understanding of what she is.
Fledgling
Sci-Fi · Genetic Engineering · Speculative Fiction
Our take
Memory becomes a survival problem when a girl wakes with violent hunger and no understanding of what she is. In Fledgling, Octavia E. Butler follows an amnesiac vampire forced to uncover her stolen past, her altered biology, and the enemies still hunting her. This speculative vampire novel examines identity, otherness, power, and humanity through a story shaped by danger and discovery.
Choose your retailer
About the book
Fledgling, Octavia Butler’s last novel, is the story of an apparently young, amnesiac girl whose alarmingly un-human needs and abilities lead her to a startling conclusion: she is in fact a genetically modified, 53-year-old vampire. Forced to discover what she can about her stolen former life, she must at the same time learn who wanted—and still wants—to destroy her and those she cares for, and how she can save herself. Fledgling is a captivating novel that tests the limits of "otherness" and questions what it means to be truly human.

About the book
New York Times Notable Book and Hugo and Nebula Award Finalist: An epic chronicle of ten immortals over the course of history from an SFWA Grand Master.
The immortals are ten individuals born in antiquity from various cultures. Immune to disease, able to heal themselves from injuries, they will never die of old age—although they can fall victim to catastrophic wounds. They have walked among mortals for millennia, traveling across the world, trying to understand their special gifts while searching for one another in the hope of finding some meaning in a life that may go on forever.
Following their individual stories over the course of human history and beyond into a richly imagined future, "one of science fiction's most revered writers" (USA Today) weaves a broad tapestry that "succeeds admirably" (The New York Times).

A soldier returns from captivity to a kingdom that would rather use him than welcome him home.
The Thirteenth Man
Sci-Fi · Galactic Empire · Military Sci-Fi · Space Opera
Our take
A soldier returns from captivity to a kingdom that would rather use him than welcome him home. When Commander Charlie Cass finds the Realm tangled in court intrigue and edging toward interstellar war, he must rely on tactical skill, stubborn resolve, and political instinct to survive. This military science fiction novel blends space opera, aristocratic conflict, and high-stakes strategy with a fast-moving sense of adventure.

About the book
From the author of The Treasons Cycle, The Gods Within, and The Dead Among Us series comes a stand-alone science fiction novel for fans of David Weber, Pierce Brown, Lois McMaster Bujold, and more! Spanning the galaxy, The Thirteenth Man blends the best traditions of space opera and military sci-fi into a non-stop adventure that's as much Patrick O'Brien as it is John Scalzi.
When Commander Charlie Cass, the bastard son of the Duke de Maris, returns from five years in a squalid Syndonese POW camp, he finds that little has changed in the Realm. As always, the King and the nine Dukes are conspiring against each other, but now some of them are plotting with Charlie's old enemy. And as interstellar war looms, they certainly don't need Charlie Cass messing up their delicate plans.
Unfortunately for them, that's what he's best at.
With ingenuity, tacticial inovations, and just a little bit of luck, Cass might be able to not only save the Realm, but perhaps even change it for the better.
Which, of course, means he'll likely face the headsman's axe.

Our take
A child with no voice and a past that defies time draws strangers together across the vast distances of space.

About the book
A “highly imaginative and utterly exhilarating” (Thrillist) debut that is “the best of what science fiction can be: a thought-provoking, heartrending story about the choices that define our lives” (Kirkus Reviews, Best Debut Fiction and Best Science Fiction & Fantasy of the Year).
FINALIST FOR THE LOCUS AWARD • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY TORDOTCOM AND KIRKUS REVIEWS
A mysterious child lands in the care of a solitary woman, changing both of their lives forever.
I expected many things from this trip. I did not expect a family.
A ship captain, unfettered from time. A mute child, burdened with unimaginable power. A millennia-old woman, haunted by lifetimes of mistakes. In this captivating debut of connection across space and time, these outsiders will find in each other the things they lack: a place of love and belonging. A safe haven. A new beginning.
But the past hungers for them, and when it catches up, it threatens to tear this makeshift family apart.
Praise for The Vanished Birds
“This is the most impressive debut of 2020.”—Locus
“This extraordinary science fiction epic, which delves deep into the perils of failing to learn from one’s mistakes, is perfect for fans of big ideas and intimate reflections.”—Publishers Weekly (starred review)
“A lyrical and moving narrative of space travel, found families, and lost loves set against an evocative space-opera background.”—Booklist (starred review)
“The Vanished Birds finds an intimate heartbeat of longing in a saga of galactic progress and its crushing fallout. . . . A novel of vast scope that yet makes time for compassion, wonder, and poetry.”—Indra Das, author of The Devourers

Best of the Year at Gizmodo, Library Journal, and more!
"An astonishing, thought-provoking and above all touching story of found meaning and lost humanity.” —Adrian Tchaikovsky, Arthur C. Clarke Award-winning author of Children of Time
Slow Gods is the galaxy-spanning tale of one man's impossible life charted against the fate of humanity amongst the stars—a powerfully imaginative space opera from multi-award-winning author Claire North, perfect for fans of A Memory Called Empire and The Vanished Birds.
My name is Mawukana na-Vdnaze, and I am a very poor copy of myself.
In telling my story, there are certain things I should perhaps lie about. I should make myself a hero. Pretend I was not used by strangers and gods, did not leave people behind.
Here is one truth: out there in deep space, in the pilot's chair, I died. And then, I was reborn. I became something not quite human, something that could speak to the infinite dark. And I vowed to become the scourge of the world that wronged me.
This is the story of the supernova event that burned planets and felled civilizations. This is also the story of the many lives I've lived since I died for the first time.

About the book
Astronomers discover an interstellar comet on a collision course with Venus. Not since Comet Shoemaker–Levy 9 struck Jupiter in 1994 has a collision captured the public's imagination, but all is not what it seems. Additional observations reveal a second comet also on a collision course with Venus, sparking speculation about the possibility of extraterrestrial involvement. NASA astronaut Dice Newman is already in space, heading to Venus to observe the impact, when confirmation comes of an alien spacecraft entering the solar system.

FIRST CONTACT is a series of stand-alone novels that explore humanity's first interaction with extraterrestrial life. This series is similar to BLACK MIRROR or THE TWILIGHT ZONE in that the series is based on a common theme rather than common characters. This allows these books to be read in any order. Technically, they're all first as they all deal with how we might initially respond to contact with aliens, exploring the social, political, religious, and scientific aspects of First Contact.

About the book
"A fascinating, compulsively readable clash of hardware and ideals" in a stand-alone space opera from an acclaimed sci-fi author (Kirkus Reviews, starred review).
In the distant future, corporations have become sustainable communities with their own militaries, and corporate goals have essentially replaced political ideology.
On a youthful, rebellious impulse, Lawrence joined the military of a corporation that he now recognizes to be ruthless and exploitative. His only hope for escape is to earn enough money to buy his place in a better corporation. When his platoon is sent to a distant colony to quell a local resistance effort, it seems like a stroke of amazing fortune, and Lawrence plans to rob the colony of their fabled gemstone, the Fallen Dragon, to get the money he needs. However, he soon discovers that the Fallen Dragon is not a gemstone at all, but an alien life form that the local colonists have been protecting since it crashed in their area. Now, Lawrence has to decide if he will steal the alien to exploit the use of its inherent biotechnical processes—which far exceed anything humans are capable of—or if he will help the Resistance get the alien home.
