Empire of Silence
Sci-Fi · Space Opera
Our take
Empire of Silence begins with a man remembered as both savior and destroyer, then strips the legend back to the choices that made him infamous. Hadrian Marlowe flees a brutal inheritance only to be stranded among gladiator pits, alien war, and imperial politics. This is sweeping space opera with epic fantasy bones, built around exile, power, memory, and the cost of becoming history.

About the book
"[E]pic science fiction at its most genuinely epic." —James S.A. Corey, New York Times-bestselling author of The Expanse novels
"This wow book is a must for fans of Pierce Brown and Patrick Rothfuss." —Library Journal (starred)
Hadrian Marlowe, a man revered as a hero and despised as a murderer, chronicles his tale in the galaxy-spanning debut of the Sun Eater series, merging the best of space opera and epic fantasy.
It was not his war.
The galaxy remembers him as a hero: the man who burned every last alien Cielcin from the sky. They remember him as a monster: the devil who destroyed a sun, casually annihilating four billion human lives—even the Emperor himself—against Imperial orders.
But Hadrian was not a hero. He was not a monster. He was not even a soldier.
On the wrong planet, at the right time, for the best reasons, Hadrian Marlowe starts down a path that can only end in fire. He flees his father and a future as a torturer only to be left stranded on a strange, backwater world.
Forced to fight as a gladiator and navigate the intrigues of a foreign planetary court, Hadrian must fight a war he did not start, for an Empire he does not love, against an enemy he will never understand.

About the book
A "dazzling" tale of empire and betrayal set among the stars (#1 New York Times bestselling author Casey McQuiston), this queer, spectacular space opera draws inspiration from Roman and Egyptian empires—and the lives and loves of Cleopatra and Julius Caesar.
Princess Altagracia has lost everything. After a bloody civil war, her twin sister has claimed both the crown of their planet, Szayet, and the Pearl of its prophecy: a computer that contains the immortal soul of Szayet’s god.
So when the interstellar Empire of Ceiao turns its conquering eye toward Szayet, Gracia sees an opportunity. To regain her planet, Gracia places herself in the hands of the empire and its dangerous commander, Matheus Ceirran.
But winning over Matheus, to say nothing of his mercurial and compelling captain Anita, is no easy feat. And in trying to secure her planet’s sovereignty and future, Gracia will find herself torn between Matheus’s ambitions, Anita’s unpredictable desires, and the demands of the Pearl that whispers in her ear.
For Szayet’s sake and her own, she will need to become more than a princess with a silver tongue. She will have to become a queen as history has never seen before.
"A glittering triumph of a book that weaves together history and tragedy into a star-spanning epic." —Everina Maxwell, author of Winter’s Orbit

About the book
The Philip K. Dick Award-winning saga of humankind's next five million years: "Mind-stretching science fiction at its boldest." —Orlando Sentinel
And everywhere the Humans went, they found life . . .
This dazzling future history, the most ambitious and exciting since Asimov's classic Foundation saga, tells the story of Humankind—all the way to the end of the Universe itself. Here, in luminous and vivid narratives spanning five million years, are the first Poole wormholes spanning the solar system; the conquest of Human planets by Squeem; GUTships that outrace light; the back-time invasion of the Qax: the mystery and legacy of the Xeelee, and their artifacts as large as small galaxies; photino birds and Dark Matter; and the Ring, where Ghost, Human, and Xeelee contemplate the awesome end of Time.
"It's old-fashioned 1950s-style science fiction . . . and it's also lots of fun." —Cleveland Plain Dealer
"Enormously impressive." —Locus

About the book
In the twenty-second century, humanity thinks it’s struck gold: limitless energy from a mysterious exchange with a parallel universe. No fuel costs. No shortages. Just endless power. Too bad it’s a ticking time bomb.
Dr. Frederick Hallam basks in fame as the face of the discovery, while obscure scientist Peter Lamont realizes the truth—Earth’s Sun is being slowly poisoned. Across the divide, alien beings also see doom looming, but their pleas for change go unheard.
Meanwhile, on the Moon, Selene Lindstrom, a lunar-born intuitionist, senses what no equations can prove: annihilation is closer than anyone admits. If no one listens, the cost of “free” energy is planetary extinction.
Three worlds. One failing star. Will truth break through before everything burns out?

Magic birds, galactic invaders, and a dragon in disguise.
Isles of the Emberdark
Fantasy · Sci-Fi · Space Exploration · Space Opera

Magic birds, galactic invaders, and a dragon in disguise. Sixth of the Dusk is Brandon Sanderson’s newest Cosmere novel, expanding his beloved novella into an epic of survival, myth, and starbound ambition.

About the book
On the deadly island of Patji, Dusk is a trapper who lives by instinct, magic, and the supernatural birds he calls Aviar. But when invaders from the stars threaten to conquer his world, he must sail into the emberdark in search of salvation—armed only with his birds, a canoe, and his hard-won survival skills.
In the emberdark, a young dragon named Starling is trapped in human form, flying with a starship crew deep in debt and desperation. When she discovers a portal that could change everything, her path collides with Dusk’s in a galaxy-spanning race for freedom.
Sixth of the Dusk expands Sanderson’s original novella into a sweeping Cosmere novel full of myth, magic, and cosmic stakes. Survival isn’t guaranteed. But legends rarely start with safety.
