Imperial Death Dealer Ethan Wolfe has been dispatched to kill a terrorist at the edge of the galaxy. It was a simple mission until the Emperor and his Lord Commander outlawed and condemned him to death, without any reason. But as he goes on the run, with Hope Adair, a former smuggler, Ethan learns that his dead father was not an archaeologist but an agent of the Empire with a terrible secret. And that secret will lead him on a quest to find an ex-Imperial soldier and a being called the Guardian. Little does he know that he has a big role to play in the coming Great War with the Fallen.

Two centuries ago, the Imperium of Man and the upstart Tau Empire fought to a standstill in the Damocles Gulf. Now, as the 41st millennium draws to a close, the tau have returned. As the world of Agrellan falls under attack, the White Scars and Raven Guard rush to its defence, but with the skilled Commander Shadowsun leading the alien forces, the Space Marines and their allies are hard pressed. Kor'sarro Khan, Huntmaster of the White Scars, swears that he will win the day in the most direct way possible – by taking Shadowsun's head.

Once dismissed as a mathematical curiosity, black holes are so strange they almost defy belief. Since their existence was confirmed, research into the nature of black holes has opened up new vistas in physics. In this audiobook, we examine some of the most fascinating discoveries about black hole formation and behavior, the new and evolving research in gravitational wave astronomy, theoretical possibilities such as wormholes, and much more.

The fearsome bounty hunter Tyrus Rechs has laid a careful trap to kill an elusive and powerful criminal known as Mister Zauro for crimes orchestrated on the planet Detron. But unbeknownst to the bounty hunter, another trap has been laid just as carefully ... a trap for Tyrus Rechs himself. For Zauro is a Lizzaar, and Lizzaar crime lords are not without their defenses. Rechs is mere moments away from finishing his termination when the counter-trap is triggered. In an instant the tables are turned, the hunter becomes the hunted.

Seven years after the indomitable Doug Stavenger has realized his cherished dream of establishing a colony on the inhospitable lunar surface, Moonbase is a thriving community, a marvel of scientific achievement created and supported by nanotechnology: virus-sized machines that can build, cure, and destroy. But nanotechnology has been declared illegal by the home planet’s leaders, and a powerful despot is determined to lay claim to Stavenger’s peaceful city - or obliterate it, if necessary.

In Saturn's Children, Freya is an obsolete android concubine in a society where humans haven't existed for hundreds of years. A rigid caste system keeps the Aristos, a vindictive group of humanoids, well in control of the lower, slave-chipped classes. So when Freya offends one particularly nasty Aristo, she's forced to take a dangerous courier job off-planet.

Humanity's thousand-year-old interstellar empire has been rotting from the inside for over a century, thanks to venal, corrupt, and power-hungry sovereigns from a dynasty many consider illegitimate. The latest in that lineage, an increasingly psychotic empress, is pushing her realm toward collapse as admirals and generals rebel against her rule. That rebellion quickly drags the once mighty Imperial Fleet into a devastating fratricidal conflict between factions.

After a series of victories, the Imperial forces are on the back foot once more. The power of Chaos is rising, the Traitors gain ground, and all hope seems lost. Can Terra endure?

Ambassador Mahit Dzmare arrives in the center of the multi-system Teixcalaanli Empire only to discover that her predecessor, the previous ambassador from their small but fiercely independent mining station, has died. But no one will admit that his death wasn't an accident - or that Mahit might be next to die, during a time of political instability in the highest echelons of the imperial court. Now, Mahit must discover who is behind the murder, rescue herself, and save her station from Teixcalaan's unceasing expansion.

Although the exciting military career she hoped for never got off the ground, Ky Vatta ended up seeing plenty of combat when she took the helm of one of the commercial transport vessels in her family's fleet...and steered it into a full-blown war. Now the lessons she learned in that trial by fire are about to pay off - because this time, the war has come to her. Someone has launched a full-throttle offensive against Vatta Transport Ltd., Ky's father's interstellar shipping empire.

The problem with lying about having a super weapon is that the bad guys might believe they have nothing to lose by doing something stupid that both sides will regret. Or, they might just call your bluff. Either way, the Merry Band of Pirates need a plan to deal with the Fallout.

Award-winning science writer and documentarian Rod Pyle presents an insider's perspective on the most unusual and bizarre space missions ever devised inside and outside of NASA. The incredible projects described here were not merely flights of fancy....

Ben Dailey's Viper Company has one motto: Play hard and fight even harder. The crew is comprised of some of the most elite fighters in the Fleet, though occasionally overconfident and, some might say, obnoxious. So when Dailey is handed down a mysterious, high-security mission that's ostensibly a search-and-rescue for his once-upon-a-time academy rival turned brother in arms, he's convinced there's more to the job than meets the eye. Soon, the USF Murphy is on its way to the edge of the Void to track down what happened to Capt. Rick Bearing and the Asher-5.

The Warmaster’s horde advances through the fire and ash of Terra's dying breaths, forcing the loyalists back to the Delphic Battlement—the very walls of the Sanctum Imperialis. Angron, Primarch of the World Eaters and Herald of Horus, has achieved immortality through annihilation—now he leads the armies of the damned in a wrathful tide, destroying all before them as the warp begins its poisonous corruption of Terra's very soil.

The destruction of the Death Star by the Rebel Alliance was a decisive blow against the Empire, but Palpatine and his monstrous enforcer, Darth Vader, are no less of a threat. The brutal extermination of Alderaan not only demonstrated the magnitude of their murderous power, but served as a chilling testament to their resolve to crush the Rebel uprising. Standing against them, Skywalker, Solo, and the Princess remain uncertain opponents. Luke is gifted and brave, but unschooled in the power he possesses.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.

With Fyrion a distant speck behind us and the resources of the Dragon’s Right Eye out of reach, there’s only one place in the system we can go to gather the materials we need to advance to bronze. Ilirian beckons. But dangers lurk in those dark jungles, and the ruins of a civilization long dead house threats the likes of which no amount of training or meditation could’ve prepared us for. It’s advance or fall behind, and with the infinite sea at my back, there’s only one real option.

The Veklocks require the Pyreans to explore the extent of the Colony's usurpation of domes. The Colony is composed of two insectoid species, the grays and the reds. They're aggressive three- and five-meter long insectoids with venomous pincers that live for the expansion of their race. The Pyreans already lost one member of their team on their first exploration and are hesitant to meet the Colony again, unless they're better prepared.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

After one great battle, the Architects disappeared. Yet humanity’s fragile peace is brief. For, 40 years later, the galaxy’s greatest alien enemy has returned. This time, the artefacts that preserved entire worlds from destruction are ineffective. And no planet is safe. The Human Colony worlds are in turmoil as they face extinction. Some believe alliances with other species can save them. Others insist humanity must fight alone. But no one has the firepower or technology to ensure victory, as the Architects loom ever closer.
