About the book
The virtual persona of a long-dead entrepreneur threatens to incite a revolution that could topple Earth's dictatorship in this science fiction classic.
In the future, individual freedom is a thing of the past. North America is a police state controlled by the Avantist government, a despotic, techno-religious ruling order that promises an impending transcendence for the oppressed. Space, however, remains free, thanks to Anson Guthrie's powerful Fireball Corporation. Guthrie's corporeal self died many generations ago, but his essence lives on, preserved forever in a computerized state that enables him to inspire his loyal employees and adherents to keep reaching for the farthest stars.
But now the totalitarian enemy, led by sadistic secret policeman Enrique Sayre, has gained possession of a Guthrie download, intending to subvert it to the Avantist cause, thereby breaking Fireball's hold on the cosmos. The corporation is doomed unless ace pilot Kyra Davis can smuggle a still-unreconstructed version of Guthrie out of enslaved America and rocket him to the moon and beyond, where Fireball's virtual creator can attempt to stoke the flames of revolution—and change the direction of his world.
A truly remarkable work, Harvest of Stars might be the most ingenious and ambitious novel of Poul Anderson's acclaimed and prolific career. Thoughtful and adventurous, rich in imagination and integrity, it offers definitive proof of the Hugo and Nebula Award–winning, Grand Master of Science Fiction's unparalleled mastery in the field of speculative fiction.

About the book
On a planet shrouded in darkness, a stranded crew must fight for survival. But, the darkness may have plans of its own in this wildly original story from Adrian Tchaikovsky, Hugo and Arthur C. Clarke Award–winning author of Children of Time.
They looked into the darkness and the darkness looked back . . .
New planets are fair game to asset strippers and interplanetary opportunists – and a commercial mission to a distant star system discovers a moon that is pitch black, but alive with radio activity. Its high-gravity, high-pressure, zero-oxygen environment is anathema to human life, but ripe for exploitation. They named it Shroud.
Under no circumstances should a human end up on Shroud’s inhospitable surface. Except a catastrophic accident sees Juna Ceelander and Mai Ste Etienne doing just that. Forced to stage an emergency landing, in a small, barely adequate vehicle, they are unable to contact their ship and are running out of time. What follows is a gruelling journey across land, sea and air. During this time, Juna and Mai begin to understand Shroud’s dominant species. It also begins to understand them . . .

About the book
Bryan Norton thought early retirement meant endless days in the Arizona desert, honing his aim and keeping to himself. A blown knee had ended his career as a Marine captain, but solitude suited him just fine.

His only hope lies aboard the Independence, a ship crewed by unlikely allies with the power to restore his strength and youth.
Retirement is officially over. The universe has other plans, and survival means becoming more than human.

About the book
Humanity’s complex relationship with technology spirals out of control in this first book of an all-new series from “the owner of the most powerful imagination in science fiction” (Ken Follett).
“How far ‘space opera’ has come! The Old Masters of sci-fi would admire the scope and sweep of Salvation.”—The Wall Street Journal
In the year 2204, humanity is expanding into the wider galaxy in leaps and bounds. Cutting-edge technology of linked jump gates has rendered most forms of transportation—including starships—virtually obsolete. Every place on Earth, every distant planet humankind has settled, is now merely a step away from any other. All seems wonderful—until a crashed alien spaceship of unknown origin is found on a newly located world eighty-nine light-years from Earth, carrying a cargo as strange as it is horrifying. To assess the potential of the threat, a high-powered team is dispatched to investigate. But one of them may not be all they seem. . . .
Bursting with tension and big ideas, Peter F. Hamilton’s Salvation is the first book of an all-new series that highlights the inventiveness of an author at the top of his game.

Our take
Andrew Moriarty’s Imperial Deserter is a sharp, fast-paced space opera full of snappy dialogue, galactic intrigue, and morally gray rogues.

Perfect for fans of witty, chaotic, character-driven sci-fi adventures.
Choose your retailer
About the book
Kill a man and you're a murderer. Kill a million and you're a statesman. Dirk should have killed more people.
Dirriken Friedel used his aristocratic connections to rescue his troops. He didn’t plan on starting a war or killing them himself. Now he spends his days in jail, waiting for an assassin sent by his dead officers families to end his misery.
When he’s broken out by off-duty marines he has a chance to start over, if he’s worthy. During his ramshackle escape he collects a broken-down trading ship, a bitter former army officer, a genetically altered religious fanatic, a runaway ingenue, a sham engineer, and a murderous femme fatal. Pursed by a fanatical imperial tribune bent on bloody justice, can he keep the crew from killing each other, the ship from exploding, and himself from the bottom of a bottle. Or would it be easier just to give up?
If you like Galactic Empires, honorable enemies, and snappy dialog, this one’s for you.

About the book
Tom Rice thought his first assignment as a graduate student would be straightforward: join a team of archaeologists and dig through the remains of an ancient alien civilization. The High Ones ruled the galaxy millennia ago, and now only fragments of their culture remain—cryptic artifacts scattered across the stars.
When the team uncovers a “message cube” containing living images of the High Ones, everything changes. The footage suggests these beings may not be extinct after all. What began as an academic mission suddenly becomes a dangerous pursuit across the cosmos.
Each discovery leads to new peril, as Tom and his crew hurtle toward answers that could rewrite humanity’s place in the universe. Some relics should be left buried. This one refuses to stay quiet.

Our take
Jamie Sawyer’s Lazarus War: Origins is a blistering sci-fi military thriller perfect for fans of Jack Campbell.

Choose your retailer
About the book
Conrad Harris has died more times than he can count. That’s why they call him Lazarus. Leading an elite military unit, Harris specializes in the impossible: high-risk missions fought in simulant bodies where death is only temporary—until it isn’t.
But the enemy they face is unlike any other. The Krell Empire has devastated humanity, leaving command desperate for a breakthrough. Harris and his war-weary team are dispatched on a mission that could finally shift the balance. The risks are staggering, the odds near impossible, and the cost of failure catastrophic.
For Lazarus, survival isn’t the challenge. It’s deciding how many times he and his team can die for a war that may never end—and whether victory is worth the sacrifice.
