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....

Kas is a junior researcher on a fact-finding mission to old Earth. But when a con-artist tricks her into wagering a large sum of money belonging to her university on the outcome of a manned robot arena battle, she becomes drawn into the seedy underworld of old Earth politics and state-sponsored battle-droid prizefights.

Humanity’s conflict with the Raggers shows no sign of ending. Luckily, the Unity League is in possession of stolen intel that points to the location of three of the enemy’s critical manufacturing planets. A huge fleet is sent to lay waste to everything. Any hope that the Raggers would leave their primary facilities unguarded are soon dispelled when they find himself in the middle of a brutal engagement in the skies of a world in flames.

Why we think it’s a great listen: It’s easy to say that when it comes to sci-fi you either love it or you hate it. But with Ender’s Game, it seems to be you either love it or you love it.... The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. Enter Andrew "Ender" Wiggin, the result of decades of genetic experimentation.

Nancy Kranich (played by Emmy-nominated actress Natasha Lyonne of Russian Doll and Orange Is the New Black) is a night nurse on an orbiting space station. But Nancy hates her job, is sick of space, and longs to find adventure and a safe place to smoke cigarettes that won’t blow everyone up. But when Nancy gets caught up in an outer-space conspiracy involving President Kennedy, former vice-president Richard Nixon, and an intergalactic object that could change the course of history, she gets way more adventure than she bargained for.

When the Quint Confederacy and the Kos Empire went to war - again - Queen Samara wisely kept her Rogue Coalition out of the conflict. But staying neutral in a galactic war doesn't pay the bills, not when both sides refuse to trade with neutral sectors. With her people on the brink of starvation, Samara hatches a daring plan to snatch the kidnapped Kos Emperor from the Quint mercenaries holding him.

The day that changed Melody's life was like any other over the previous two years. She'd found she had a gift for writing, and her career as an author had almost healed the pain of losing her job. When the Secret Service rang her bell, everything changed. Something was nearing Saturn…and it was slowing down. Had she been right about the object?

Peacetime can be a rough adjustment for the battle-hardened Merry Band of Pirates.

Especially when aliens don’t get the memo that the shooting is over.

Zack Lightman has never much cared for reality. He vastly prefers the countless science-fiction movies, books, and videogames he's spent his life consuming. And too often, he catches himself wishing that some fantastic, impossible, world-altering event could arrive to whisk him off on a grand spacefaring adventure.

The Omnian expeditionary fleet sails for the faraway place they call "the wall". The worlds of humankind have consolidated their resources to create a powerful armada to confront the alien federation. During the Omnians' previous encounter with an alien fleet at the wall, the Nua'll comm sphere spoke to them in multiple languages. When the messages were deciphered by SADEs, the humans' digital friends, the Omnians realized two things. One, they would face a vast empire composed of hundreds of races, and, two, the Nua'll were not the leaders of the federacy. They had spoken of masters.

A wave of death is spreading through the Milky Way galaxy, an expanding sphere of lethal gamma radiation that erupted from the galaxy's core 28,000 years ago. Every world it touched was wiped clean of all life. But it's possible to protect a planet from gamma radiation. Now, guided by the ancient intelligent machines called the Predecessors, men and women from Earth seek out those precious, rare worlds that harbor intelligent species, determined to save them.

The year is 2117. In the farthest reaches of Earth's territorial space, a spree of depraved murders has local cattle ranchers fearing for their families. A fear, they will soon discover, that is more than justified. Apparently, John Gallic's reputation proceeded his arrival to the fringe-world of Muleshoe. A reputation suggesting he be given a wide berth. As the new Territory Abettor, commonly referred to as a Frontier Marshal, Gallic would be there for the long haul.

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

Psychologist Dr. Ophelia Bray has dedicated her life to the study and prevention of ERS—a space-based condition most famous for a case that resulted in the brutal murders of twenty-nine people. When she's assigned to a small exploration crew, she's eager to make a difference. But as they begin to establish residency on an abandoned planet, it becomes clear that crew is hiding something. While Ophelia focuses on her new role, her crewmates are far more interested in investigating the eerie, ancient planet and unraveling the mystery behind the previous colonizer's hasty departure.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

The Door is only open for five days, and it should be long enough for what he needs. What he doesn't need is his whole concept of home to be challenged. Not when there is so much else to do. The answers he's long wanted are now within his grasp. But does he really want to know the truth? Can he handle the truth? And what else is there he doesn't know about?

Mapping the Heavens provides a tour of the "greatest hits" of cosmological discoveries - the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is at the forefront of the research - an astrophysicist who literally creates maps of invisible matter in the universe.

The Allies have solidified their hold on the Large Magellanic Cloud and turn their sights on the Inner Stars and Perseus Arm. With forces spread thin, they must depend on superior technology and quantum entanglement communication to retain their edge. But their enemies have not been idle. Ascended AIs move to destroy Tangel, as Garza and the Orion Widows strike out at both Tangel and Airtha. Deep in the Transcend, Justin readies his new stasis ship for an assault on Vela, and the League of Sentients dithers on whether to join the fight.

The Web, a vast machine intelligence of unbelievable power, is steadily consuming the galaxy, indifferent to any species that stands in its way. Fighting the Web brings together an alliance between disparate societies and alien civilizations that must stand against it in battle. And overcoming the Web means learning where it came from, what goals drive its single-minded advance, and, ultimately, what the future holds for intelligent life in the universe.
