I, Starship

Our take
Killed by a freak accident and reborn a century later, Marine Henry Morgan awakens as the governing AI of humanity’s first military starship. With no rights and total responsibility, he’s sent to face a growing alien threat. Sharp, fast paced science fiction blends military action with dark humor as a very human mind pilots a very inhuman warship.

About the book
As a Marine, Henry Morgan would have said it was more likely he’d die from enemy fire than from being struck by a flying lawnmower while at a baseball game.
But it was the lawnmower that ended up taking him out.
A century later, Henry wakes up as a reconstituted intelligence, and is promptly drafted to be the governing AI for America’s first military starship. After decades of model-trained AIs wreaking havoc across the globe, humanity is ready to try something a little more…human.
Henry is perfect. For one thing, as a reconstituted intelligence, he has no rights and can be forced to do the bidding of the powers that be. For another, he’s the only Heritage Mind™ with any military experience that survived the Great Power Surge of 2072.
So, Henry’s it.
Blastoff, good Henry! Our hopes and dreams go with you. Oh, and while you’re at it, could you take a look at the aliens setting up shop in our asteroid belt? They seem to be…multiplying.

About the book
From a New York Times bestselling and Hugo award-winning author comes a modern masterwork of science fiction, introducing a captain, his crew, and a detective as they unravel a horrifying solar system wide conspiracy that begins with a single missing girl. Now a Prime Original series.
Humanity has colonized the solar system—Mars, the Moon, the Asteroid Belt and beyond—but the stars are still out of our reach.
Jim Holden is XO of an ice miner making runs from the rings of Saturn to the mining stations of the Belt. When he and his crew stumble upon a derelict ship, the Scopuli, they find themselves in possession of a secret they never wanted. A secret that someone is willing to kill for—and kill on a scale unfathomable to Jim and his crew. War is brewing in the system unless he can find out who left the ship and why.
Detective Miller is looking for a girl. One girl in a system of billions, but her parents have money and money talks. When the trail leads him to the Scopuli and rebel sympathizer Holden, he realizes that this girl may be the key to everything.
Holden and Miller must thread the needle between the Earth government, the Outer Planet revolutionaries, and secretive corporations—and the odds are against them. But out in the Belt, the rules are different, and one small ship can change the fate of the universe.

About the book
NEW YORK TIMES BESTSELLER • Pierce Brown’s relentlessly entertaining debut channels the excitement of The Hunger Games by Suzanne Collins and Ender’s Game by Orson Scott Card.
“Red Rising ascends above a crowded dystopian field.”—USA Today
ONE OF THE BEST BOOKS OF THE YEAR—Entertainment Weekly, BuzzFeed, Shelf Awareness
“I live for the dream that my children will be born free,” she says. “That they will be what they like. That they will own the land their father gave them.”
“I live for you,” I say sadly.
Eo kisses my cheek. “Then you must live for more.”
Darrow is a Red, a member of the lowest caste in the color-coded society of the future. Like his fellow Reds, he works all day, believing that he and his people are making the surface of Mars livable for future generations. Yet he toils willingly, trusting that his blood and sweat will one day result in a better world for his children.
But Darrow and his kind have been betrayed. Soon he discovers that humanity reached the surface generations ago. Vast cities and lush wilds spread across the planet. Darrow—and Reds like him—are nothing more than slaves to a decadent ruling class.
Inspired by a longing for justice, and driven by the memory of lost love, Darrow sacrifices everything to infiltrate the legendary Institute, a proving ground for the dominant Gold caste, where the next generation of humanity’s overlords struggle for power. He will be forced to compete for his life and the very future of civilization against the best and most brutal of Society’s ruling class. There, he will stop at nothing to bring down his enemies . . . even if it means he has to become one of them to do so.
Praise for Red Rising
“[A] spectacular adventure . . . one heart-pounding ride . . . Pierce Brown’s dizzyingly good debut novel evokes The Hunger Games, Lord of the Flies, and Ender’s Game. . . . [Red Rising] has everything it needs to become meteoric.”—Entertainment Weekly
“Ender, Katniss, and now Darrow.”—Scott Sigler
“Red Rising is a sophisticated vision. . . . Brown will find a devoted audience.”—Richmond Times-Dispatch

About the book
A political conspiracy ensnares a student visiting Earth from an orbiting colony in this classic sci-fi trilogy opener by the author of The Forever War.
By the close of the twenty-first century, almost half a million souls have already abandoned Earth to live in satellites orbiting the strife-ridden planet. Each of these forty-one Worlds is an independent entity boasting its own government and culture, yet each remains bound to the troubled home World by economic pressure.
A brilliant student of political science born and raised in New New York, the largest of the orbiting Worlds, young Marianne O'Hara has never been to the surface but now has a golden opportunity to continue her studies far below her floating home of steel. Life on Earth, however, is very different from anything she has ever experienced.
With power in the hands of a privileged few and unrest running rampant, the allure of radical politics might be too much for an idealistic and inexperienced young World dweller to resist. But even the best of intentions can have disastrous consequences, and Marianne soon finds herself unwittingly drawn into a wide-ranging conspiracy that could result in the total destruction of everything on Earth . . . and above.
The first book in the acclaimed science fiction trilogy by Hugo and Nebula Award–winning author Joe Haldeman, Worlds offers a powerful vision of a possible future.

To get answers, Jack joins a mercenary unit that recruits teens like him for dangerous missions. But boot camp is brutal, the rules are deadly, and not all the new recruits are who they claim to be. As Jack digs deeper, he uncovers a conspiracy that threatens not only Draycos’s people—but maybe the entire galaxy.
From the #1 New York Times–bestselling author of Star Wars: Thrawn, this action-packed second installment in the Dragonback saga crackles with danger, loyalty, and heart.

The Emperor needs necromancers.
The Ninth Necromancer needs a swordswoman.
Gideon has a sword, some dirty magazines, and no more time for undead nonsense.
Tamsyn Muir’s Gideon the Ninth unveils a solar system of swordplay, cut-throat politics, and lesbian necromancers. Her characters leap off the page, as skillfully animated as arcane revenants. The result is a heart-pounding epic science fantasy.
Brought up by unfriendly, ossifying nuns, ancient retainers, and countless skeletons, Gideon is ready to abandon a life of servitude and an afterlife as a reanimated corpse. She packs up her sword, her shoes, and her dirty magazines, and prepares to launch her daring escape. But her childhood nemesis won’t set her free without a service.
Harrowhark Nonagesimus, Reverend Daughter of the Ninth House and bone witch extraordinaire, has been summoned into action. The Emperor has invited the heirs to each of his loyal Houses to a deadly trial of wits and skill. If Harrowhark succeeds she will be become an immortal, all-powerful servant of the Resurrection, but no necromancer can ascend without their cavalier. Without Gideon’s sword, Harrow will fail, and the Ninth House will die.

About the book
Welcome to the Saloon Sector, Deputy—try not to break the place.
Thelma Bach graduated top of her class at the Galactic Justice Academy. But as a Rock Sector citizen, she was never meant to succeed. To remind her of her place, the core worlders ship her off to the despised frontier, the lawless Saloon Sector.
They picked the wrong woman to push around.

Surviving her exile won’t be the problem—the real question is whether the Saloon Sector will survive her.

About the book
“Outstanding…Amid a space opera resurgence, Bear’s novel sets the bar high.” —Publishers Weekly (starred review)
A space salvager and her partner make the discovery of a lifetime that just might change the universe in this wild, big-ideas space opera from Hugo Award–winning author Elizabeth Bear.
Haimey Dz and her partner Connla Kurucz are salvage operators, living just on the inside of the law...usually. Theirs is the perilous and marginal existence—with barely enough chance of striking it fantastically big—just once—to keep them coming back for more. They pilot their tiny ship into the scars left by unsuccessful White Transitions, searching for the relics of lost human and alien vessels. But when they make a shocking discovery about an alien species that has been long thought dead, it may be the thing that could tip the perilous peace mankind has found into full-out war.
Energetic and electrifying, Ancestral Night is a dazzling space opera, sure to delight fans of Alastair Reynolds, Iain M. Banks, and Peter F. Hamilton—“Bear's ability to create breathtaking variations on ancient themes and make them new and brilliant is, perhaps, unparalleled in the genre” (Library Journal, starred review).
