In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

Corta Hélio, one of the five family corporations that rule the moon, has fallen. Its riches are divided up among its many enemies, its survivors scattered. Eighteen months have passed. The remaining Hélio children, Lucasinho and Luna, are under the protection of the powerful Asamoahs, while Robson, still reeling from witnessing his parents' violent deaths, is now a ward - virtually a hostage - of Mackenzie Metals. And the last appointed heir, Lucas, has vanished from the surface of the moon.

Their leaders want Nona to be the weapon that will save them from the Nine Houses.

The Sith Empire is in flux. The Emperor is missing, presumed dead, and an ambitious Sith lord’s attempt to seize the throne has ended fatally. Still, Darth Karrid, commander of the fearsome Imperial battle cruiser Ascendant Spear, continues her relentless efforts to achieve total Sith domination of the galaxy. But Karrid’s ruthless determination is more than matched in the steely resolve of Theron Shan, whose unfinished business with the Empire could change the course of the war for good. Though the son of a Jedi master, Theron does not wield the Force - but like his renowned mother, the spirit of rebellion is in his blood.

Monsters, saviors, and weapons - the Vanguard don't care what they're called. All that matters is that they answer the call when people cry out in need.

The Maurakians, bearing new technology, can go wherever they want; with little warning, the blanket of safety that humanity has created is ripped away.

But when Captain Bill Henderson is sent to claim a small moon for his masters, he finds something they never accounted for. An ancient warship – a behemoth abandoned for millennia by a species that reached its peak at the dawn of the universe.

On the planet Tython, the ancient Je’daii order was founded. And at the feet of its wise Masters, Lanoree Brock learned the mysteries and methods of the Force - and found her calling as one of its most powerful disciples. But as strongly as the Force flowed within Lanoree and her parents, it remained absent in her brother, who grew to despise and shun the Je’daii, and whose training in its ancient ways ended in tragedy. Now, from her solitary life as a Ranger keeping order across the galaxy, Lanoree has been summoned by the Je’daii Council on a matter of utmost urgency.

In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most listeners, this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it appears. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where, at the most fundamental level, time disappears.

As METAtropolis: Green Space moves into the 22nd Century, human social evolution is heading in new directions after the Green Crash and the subsequent Green Renaissance. Nearly everyone who cares to participate in the wired world has become part of the "Internet of things", a virtual environment mapped across all aspects of the natural experience. At the same time, the serious back-to-the-land types have embraced a full-on paleo lifestyle, including genetically engineering themselves and their offspring.

On September 11, 1999, humanity made a monumental discovery in the vastness of space. Scientists uncovered an asteroid of immense scientific importance—a colossal celestial entity. As massive as an aircraft carrier and towering as high as the iconic Empire State Building, this cosmic titan was later named Bennu. Remarkable for much more than its size, Bennu belonged to a rare breed of asteroids capable of revealing the essence of life itself. But just as Bennu became a beacon of promise, researchers identified a grave danger.

For the handful of scattered Jedi, survival is imperative if the light side of the Force is to be protected and the galaxy somehow, someday reclaimed. Yet more important still is the well-being of the twin infants, Leia and Luke Skywalker, the children of Anakin and his doomed bride, Padme Amidala. Separated after Padme's death, they must be made safe at all costs, lest the hope they represent for the future be turned to horror by the new Sith regime, and the unspeakable power of the dark side.

Caleb Mitchell gave up everything to protect his home. Shunned by friends and family for abandoning the pacifist beliefs of their religion, abandoned by the love of his life, he left his home world of Canaan to go to the Commonwealth Military Academy on Earth and train to fight in the looming war against the implacable alien threat of the Tahni Imperium. When a training mission with a crew of cadets winds up caught in the middle of one of the worst battles of the war, Cal and his fellow students are officially declared dead.

Gunnery Sergeant Torin Kerr was a Confederation Marine's marine. She'd survived more deadly encounters---and kept more of her officers and enlistees alive---than anyone in the Corps, and she was determined to keep that record intact. But since her last mission, she'd been sidelined into endless briefings and debriefings with no end in sight. So, of course, she'd jumped at the chance to go to Crucible---the Marine Corps training planet---as a temporary aide to Major Svensson.

An AI overseer and a human crew arrive on a distant planet to salvage an ancient UN starship. The overseer is unhappy. The crew, well, they're certainly no A-team. Not even a C-team on the best of days. And worse? Urmahon Beta, the planet, is at the ass-end of nowhere. Everybody expects this to be a long, ugly, and thankless job. Then it all goes disastrously wrong. What they thought was an uninhabited backwater turns out to be anything but empty.
