In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

Dennis E. Taylor, author of the best-selling Bobiverse trilogy, explores a whole different, darker world in this sci-fi stand-alone.

The ice is coming. It was the last thing we expected, but the world is freezing. A new ice age has dawned. Billions have fled the glaciers. A cataclysmic war is coming. In orbit, a group of scientists are running the Winter Experiments, a last-ditch attempt to understand why the planet is cooling. None of the climate models they build make sense. But then they discover an anomaly, an unexplained variation in solar radiation...and something else. Close to the burning edge of the sun, they catch a fleeting glimpse of something that shouldn’t be there....

From the Audie-nominated narrator of The Martian. In eleven years' time, a million members of an alien race will arrive at Earth. Years before they enter orbit, their approach will be announced by the flare of a thousand flames in the sky, their ships' huge engines burning hard to slow them from the vast speeds needed to cross interstellar space. These foreboding lights will shine in our night sky like new stars, getting ever brighter until they outshine even the sun, casting ominous shadows and banishing the night until they suddenly blink out.

The United States government is given a warning by the preeminent biophysicists in the country: current sterilization procedures applied to returning space probes may be inadequate to guarantee uncontaminated re-entry to the atmosphere.

What if you found a way to send something back in time? But not weeks, days, or even minutes back. What if you could only send something back a fraction of a second? Would this be of any use? You wouldn't have nearly enough time to right a wrong, change an event, or win a lottery. Nathan Wexler is a brilliant physicist who thinks he's found a way to send matter a split second back into the past. But before he can even confirm his findings, he and his wife-to-be, Jenna Morrison, find themselves in a battle for their very lives.

Former naval doctor Peter Crane is summoned to a remote oil platform in the North Atlantic to help diagnose a bizarre medical condition. But when he arrives, Crane learns that the real trouble lies far below on "Deep Storm", a stunningly advanced science-research facility built two miles beneath the surface on the ocean floor. The top-secret structure has been designed for one purpose: to excavate a recently discovered undersea site that may hold the answers to an ancient mystery.

In 1948, an alien starship crash-landed in the New Mexico desert and brought with it the key to mankind’s future. Code-named the Rho Project, the landing was shrouded in secrecy, and only the highest-ranking US government and military personnel knew it existed. Until now....

The Covenant mission is the most ambitious endeavor in the history of Weyland-Yutani. A ship bound for Origae-6, carrying 2,000 colonists beyond the limits of known space, this is a make-or-break investment for the corporation - and for the future of all mankind. Yet there are those who would die to stop the mission. As the colony ship hovers in Earth orbit, several violent events reveal a deadly conspiracy to sabotage the launch.

Neanderthals have developed a radically different civilization on a parallel Earth. A Neanderthal physicist, Ponter Boddit, accidentally passes from his universe into a Canadian underground research facility. Fortunately, a team of human scientists, including expert paleo-anthropologist Mary Vaughan, promptly identifies and warmly receives Ponter. Solving the language problem and much else is a mini-computer, called a Companion, implanted in the brain of every Neanderthal. But it can't help his fellow scientist back in his world, Adikor Huld, when the authorities charge Adikor with his murder.

In 2157, a mysterious gas known as Variant spreads across the globe, killing or mutating most organic life. The surviving humans take refuge in an underground city, determined to return home. But after generations of failures and botched attempts, hope is beginning to dwindle. That is, until a young scientist makes a unique discovery, and everything changes. Suddenly, there's reason to hope again, and it rests within a group of genetically engineered children that are both human and Variant.

Joel Byram is an everyday 22nd century guy. He spends his days training artificial-intelligence engines to act more human, jamming out to 1980s new wave - an extremely obscure genre - and trying to salvage his deteriorating marriage. Joel is pretty much an everyday guy with everyday problems - until he's accidentally duplicated while teleporting. Now Joel must outsmart the shadowy organization that controls teleportation, outrun the religious sect out to destroy it, and find a way to get back to the woman he loves.

In this prequel to Eon, Greg Bear continues to explore the possibilities presented by the asteroid Thistledown, a remnant of a lost human civilization. The Way is a tunnel through space and time that leads to other worlds, some more like planet Earth than Earth itself. It is perhaps the most formidable discovery in Thistledown and with it come disputes as to the nature of the Way and how it should be used. The Way can be reached only through Axis City, the only space station of Thistledown.

From a remote corner of the galaxy, a message is being sent. The continuous beats of a pulsar have become odd, irregular, and artificial. It can only be a code.
