About the book
The Starship Rhea’s crew has just made a groundbreaking discovery: a cluster of carbon planets radiating powerful quantum energies. Lieutenant T’Ryssa Chen, a half-Vulcan with a rare talent for interspecies connection, encounters strange life-forms there, sparking hopes of a new understanding.
But chaos erupts when the Rhea comes under sudden attack by the Einstein, a Starfleet vessel overtaken by the Borg. Stranded on the planet, Chen and her team listen in horror as their comrades are assimilated above. Just as all seems lost, she’s transported two thousand light-years away—by the beings themselves.
These beings control a quantum slipstream that the Borg are desperate to possess. With Captain Picard’s mission clear, will Starfleet stop the Borg before they access the ultimate weapon?

Our take
A shattered planet. A crew of outcasts. And Caiden, caught between survival and vengeance. With only a sentient ship and a few alien misfits by his side, Caiden must destroy the slavers who stole everything from him—even if it means risking everything he has left. One wrong move, and he’s history.
Choose your retailer
About the book
The planet he called home? Obliterated. Caiden’s family? Gone. His only shot at survival? A patched-up ship with a life of its own and a ragtag crew of aliens who aren’t exactly winning any popularity contests. Caiden’s about to learn that this universe is far bigger—and a whole lot stranger—than he ever bargained for. But the wonders of space have their darker corners, and Caiden has one goal: take down the slavers who wiped out his people. To do that, he’ll have to infiltrate their ranks, play the long game, and pray they don’t see through his plans. Because if he fails? He risks losing the one chance he has to get even. Can he succeed—or is he doomed to die trying?

Starfarers

Discovery demands a price measured in centuries.

Starfarers
Poul Anderson
Sci-Fi · First Contact · Space Exploration
Our take
Discovery demands a price measured in centuries. In Starfarers, a crew of explorers leaves Earth to pursue first contact with distant alien civilizations, knowing their home will age thousands of years in their absence. As the Envoy travels into deep space, scientific wonder collides with sacrifice in a far-reaching science fiction epic shaped by time, change, and human ambition.
Choose your retailer
About the book
Courageous space explorers embark on a mission to make contact with alien races light years away, while the Earth they leave behind ages twelve hundred centuries
It's the most exciting discovery since humankind first began watching the skies: SETI scientists detect starship "trails" in a galaxy many light years from Earth, and at long last the dream of human-to-alien contact is attainable. But the courageous crew of starfarers assembled to take on the monumental endeavor must sacrifice the only lives they've ever known and the people they love; the Earth will have aged many thousands of years when—and if—they are finally able to return. Still, their hunger for knowledge of the universe and the extraterrestrial races that inhabit it is too great to deny, and the Envoy rockets off into the vast unknown. It's a perilous mission that will profoundly change everyone it touches—even as the passing millennia transform the Earth in ways no one could ever have imagined.
Of all the science fiction extrapolators to emerge in the twentieth century, none were more visionary and few as prolific as the great Poul Anderson. Starfarers, his ingeniously imagined space exploration adventure, still stands tall among the most intelligent, enthralling, and unforgettable science fiction novels ever written.

About the book
#1 NEW YORK TIMES BESTSELLER • Now a major motion picture starring Ryan Gosling, directed by Phil Lord and Christopher Miller, with a screenplay by Drew Goddard
A lone astronaut must save the earth from disaster in this “propulsive” (Entertainment Weekly), cinematic thriller full of suspense, humor, and fascinating science—from the author of The Martian.
HUGO AWARD FINALIST • NEW YORK TIMES READER PICK: 100 BEST BOOKS OF THE 21ST CENTURY • ONE OF THE YEAR’S BEST BOOKS: Parade, Newsweek, New York Public Library, Polygon, Shelf Awareness, She Reads, Kirkus Reviews, Library Journal
Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish.
Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.
All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.
His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species.
And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone.
Or does he?
Hailed by USA Today as “an epic story of redemption, discovery, and cool speculative sci-fi,” Project Hail Mary is an irresistible interstellar adventure as only Andy Weir could deliver.
