Definition of the "Science Fiction Genre": The focus of this subgenre of fiction is science and technology, especially as they will possibly exist in a future time. Some of the typical aspects of a Science Fiction ebook are time travel, future worlds with technology that may not even be contemplated at this point, aliens and other life forms, and travelling in space. What separates the Science Fiction subgenre from the Fantasy subgenre of fiction is that the imagined or invented elements of a Science Fiction novel typically have more of a probability of existing. They are based upon scientific principles, not principles of magic.
Some examples of bestselling ebooks in the Science Fiction genre are Frank Herbert (Dune), Isaac Asimov (Foundation), Orson Scott Card (Ender's Game) and George Orwell (1984).

Join the Games to give humanity a fighting chance to survive...
OR ROLL OVER AND DIE...
Too bad for them, Warren isn't the rolling over type.
Cancer may be kicking Warren's a*&, but he's not about to let aliens destroy his home and everything he loves (which is mostly just his dog, Buck).
Besides, what does he have to lose?
Better to die with sword in hand, bleeding out from a head wound, than in some hospital bed...
...his insides shriveled up by an enemy he can't punch.
Once the games begin, Warren can't help but think,
'Maybe hospital beds aren't so bad after all.'
Nah, F-that! If you're going to go out, might as well go out having an impaled taraza (whatever the hell that is) at the end of your blade.

Once, Alistair Kane was the Commonwealth's deadliest Titan warrior. Now he's marked for execution—his only crime? Mercy.
Rescued by the very rebels he hunted, Alistair undergoes a forbidden transformation. Enhanced abilities. Mutant powers. A price paid in burning red eyes and genetic corruption.
But his physical changes pale against the searing truth: everything he fought for was a lie.
The Commonwealth's iron grip hides a darker purpose. Ancient technologies promise humanity's salvation—or its
extinction. And Alistair's loyalty to his former brothers-in-arms is about to be tested in blood.
Across nine explosive books, Alistair must unite a broken rebellion, master forbidden powers, and become the leader who can challenge an empire.
But the Commonwealth never forgets a traitor.
Can Alistair forge an army from scattered rebels before the Commonwealth's elite warriors hunt him down? And when forced to choose between saving humanity and rescuing his captive wife, which price is too high to pay?

Some shadows protect you…others will kill you in this dazzling new fantasy series from award-winning author Abigail Owen.
Everything about my life is a lie. As a hidden twin princess, born second, I have only one purpose—to sacrifice my life for my sister if death comes for her. I’ve been living under the guise of a poor, obscure girl of no standing, slipping into the palace and into the role of the true princess when danger is present.
Now the queen is dead and the ageless King Eidolon has sent my sister a gift—an eerily familiar gift—and a proposal to wed. I don’t trust him, so I do what I was born to do and secretly take her place on the eve of the coronation. Which is why, when a figure made of shadow kidnaps the new queen, he gets me by mistake.
As I try to escape, all the lies start to unravel. And not just my lies. The Shadowraith who took me has secrets of his own. He struggles to contain the shadows he wields—other faces, identities that threaten my very life.
Winter is at the walls. Darkness is looming. And the only way to save my sister and our dominion is to kill Eidolon…and the Shadowraith who has stolen my heart.
NAMED A NEW YORK TIMES NOTABLE BOOK OF THE YEAR & ONE OF THE BEST FANTASY NOVELS OF THE YEAR
“Astonishing and pristine, the kind of debut I love to be devastated by, already so assured and sophisticated that it’s difficult to imagine where the author can go from here. . . . It’s simply a delight from start to finish.” – AMAL EL-MOHTAR, New York Times Book Review
“Follow where this novel leads and you will be lost in a bewitching spell, a book of magic about books of magic . . . extraordinary.” – MARLON JAMES
In this spellbinding debut novel, two estranged half-sisters tasked with guarding their family’s library of magical books must work together to unravel a deadly secret at the heart of their collection—a tale of familial loyalty and betrayal, and the pursuit of magic and power.
For generations, the Kalotay family has guarded a collection of ancient and rare books. Books that let a person walk through walls or manipulate the elements—books of magic that half-sisters Joanna and Esther have been raised to revere and protect.
All magic comes with a price, though, and for years the sisters have been separated. Esther has fled to a remote base in Antarctica to escape the fate that killed her own mother, and Joanna’s isolated herself in their family home in Vermont, devoting her life to the study of these cherished volumes. But after their father dies suddenly while reading a book Joanna has never seen before, the sisters must reunite to preserve their family legacy. In the process, they’ll uncover a world of magic far bigger and more dangerous than they ever imagined, and all the secrets their parents kept hidden; secrets that span centuries, continents, and even other libraries . . .
In the great tradition of Ninth House, The Magicians, and Practical Magic, this is a suspenseful and richly atmospheric novel that draws readers into a vast world filled with mystery and magic, romance, and intrigue—and marks the debut of an extraordinary new voice in speculative fiction.
"Ink Blood Sister Scribe is so many things at once: an adventure, a puzzle, a twisty thriller, and a tender romance. . . . I adored it.” – ALIX E. HARROW

Instant #1 New York Times Bestseller from the author of The Poppy War
“Absolutely phenomenal. One of the most brilliant, razor-sharp books I've had the pleasure of reading that isn't just an alternative fantastical history, but an interrogative one; one that grabs colonial history and the Industrial Revolution, turns it over, and shakes it out.” -- Shannon Chakraborty, bestselling author of The City of Brass
From award-winning author R. F. Kuang comes Babel, a thematic response to The Secret History and a tonal retort to Jonathan Strange & Mr. Norrell that grapples with student revolutions, colonial resistance, and the use of language and translation as the dominating tool of the British empire.
Traduttore, traditore: An act of translation is always an act of betrayal.
1828. Robin Swift, orphaned by cholera in Canton, is brought to London by the mysterious Professor Lovell. There, he trains for years in Latin, Ancient Greek, and Chinese, all in preparation for the day he’ll enroll in Oxford University’s prestigious Royal Institute of Translation—also known as Babel.
Babel is the world's center for translation and, more importantly, magic. Silver working—the art of manifesting the meaning lost in translation using enchanted silver bars—has made the British unparalleled in power, as its knowledge serves the Empire’s quest for colonization.
For Robin, Oxford is a utopia dedicated to the pursuit of knowledge. But knowledge obeys power, and as a Chinese boy raised in Britain, Robin realizes serving Babel means betraying his motherland. As his studies progress, Robin finds himself caught between Babel and the shadowy Hermes Society, an organization dedicated to stopping imperial expansion. When Britain pursues an unjust war with China over silver and opium, Robin must decide…
Can powerful institutions be changed from within, or does revolution always require violence?

But when vast ships suddenly appear over Moscow and vacuum up 50,000 people in a matter of hours, she realizes she must track down the elusive Rains.

Drawn back into a world of interstellar conspiracy and dangerous militias, Carson faces a decision that could alter the fate of not just the Bulwark, but perhaps the entire galaxy: risk everything to help old allies or turn his back and let the chaos close in.
