For centuries, men and women have manned lighthouses to ensure the safe passage of ships. It is a lonely job and a thankless one for the most part. Until something goes wrong. Until a ship is in distress. In the twenty-third century, this job has moved into outer space. A network of beacons allows ships to travel across the Milky Way at many times the speed of light. These beacons are built to be robust. They never break down. They never fail. At least, they aren’t supposed to.

Paradise falls. Humanity is thrown back to an age of steel and blood. Now the fuel that powers the "changed" world is up for grabs in an orbiting spacecraft. With only days to plan, rough and ready paladin Herzer Herrick must assemble a team of expert warriors capable of both seat-of-the-pants engineering and hand-to-hand combat in space. In the meantime, Herzer must face his own demons. And if that's not enough, there's a horde of "changed" orcs and goblins who are intent on delivering the power above to their totalitarian masters below.

For two years, the Castle Federation and the Alliance of Free Stars have stood against Marshal James Walkingstick of the Terran Commonwealth and his mission of conquest. Battles have been won and lost, worlds have died, and soldiers like Admiral Kyle Roberts have been forged on the anvil of war. But the Alliance cannot win. The Commonwealth has more worlds, more ships, more soldiers. They claim their victory is inevitable. That history is on their side. Refusing to accept the Commonwealth's future, the Alliance embarks on a do-or-die mission to end the war in one strike.

When asubatomic physics experiment causes a massive explosion, interdimensional gateways open in Florida - and aliens pour out. Some intend to bring Earth to its knees. Others seem willing to help, but will annihilate the planet if Navy SEAL Command Master Chief Robert Miller can't stop the menace from spreading.

Pyre's humans suffer multiple cultural shocks. They discovered the Messinants dome, an ancient construction that houses a quantum-coupled gate. More shocking, they find that sentient alien races utilize a network of these domes to journey between their far distant worlds in pursuit of alliance matters. If humans wish to join this elite collection of sentients, they must contribute significantly in trade, tech, or something of equal value.

Captain Kyle Roberts has commanded the carrier Avalon through the most vicious battles of the war against the Terran Commonwealth - but with Avalon in for repair, his political enemies deny him a new ship. Unwilling to accept a desk, he takes command of a covert operation using a captured Commonwealth warship to strike at the very heart of their enemy, drawing away the reinforcements that could destroy the Alliance's recent gains.

An attitude? Why not? After all, what would you do if you were abducted by aliens and transported into a strange new universe away from your home, your family - everything familiar to you? Would it make you happy? Not likely! Now imagine you're stronger, faster, and more coordinated than every alien species you encounter. Would you start kicking some ass? Of course you would! This is the story of human superiority in the galaxy, a gritty, realistic profile of a young Navy SEAL who doesn't like aliens very much - and he makes them pay for the bad mood he's in.

With wonder, wit, and flair - and in record time and space - geophysicist David Bercovici explains how everything came to be everywhere, from the creation of stars and galaxies to the formation of Earth's atmosphere and oceans to the origin of life and human civilization. Bercovici marries humor and legitimate scientific intrigue, rocketing listeners across nearly 14 billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis.

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

When a mysterious alien probe materializes from Jump Space and remotely reprograms The Bay's star drive, Sam and his crew begin an involuntary voyage that takes them three thousand light years out of known space, across the galactic rift to the Sagittarius Spiral Arm, and into the heart of an ancient, previously unknown civilization - the first encountered by Humans and the other five races of the Cottohazz-Stellar Commonwealth - in over a century. The genetically altered immortals known as the Guardians soon turn murderously violent.

Major Rodger Y. Murphy should have died when his helicopter crashed off the coast of Mogadishu in November, 1993. Instead, he woke up in August, 2125, in a binary star system 152 light years from home. Without any memory of the otherworldly abductors who spirited them away in cold sleep, Murphy and 100 other “Lost Soldiers” have been retrieved and awakened by officers of the Consolidated Terran Republic. Promising to return to the 55 Tauri B system after completing a distant mission, they leave the twentieth century castaways with a daunting objective.

Trantor had extended its rule over half the Galaxy, but the other half defied its authority, defending their corrupt fiefdoms with violence and repression. On the planet Florina, the natives labored as slaves for their arrogant masters on nearby Sark. But now both worlds were hurtling toward a cataclysmic doom, and only one man knew the truth - a slave unaware of the secret knowledge locked inside his own brain. Rik had once been a prominent scientist until a psychic probe erased all memories of his past. Now he was a humble laborer in the kyrt mills of Florina.

Recovering from their first mission, the crew of the Vorpal Blade - humankind's first interstellar craft - is called into emergency action when an alliance gate colony is attacked. Who was the lethal alien enemy? What exactly happened at the colony? And dare the Vorpal Blade's battle-weary misfits engage a potentially superior force?

The planet Korwar was a glittering jewel of a world, inhabited by the galaxy's wealthiest, visited by the upper classes of other worlds in search of diversion. The jewel had a flaw: the Dipple, its name coming from a contraction of "displaced person", where the misfits, the hopeless, the penniless eke out a wretched existence on the dole. Two young men hoped to escape from the Dipple.

A strange body that refuses to obey you; a weird game you can't quit until your contract expires; a world teeming with powerful and very real enemies. The game in which your reputation and faction relationship are the only things that matter. These are the conditions of the agreement Ruslan signs without reading. The only thing he remembers is that he's been contracted to command a space fleet in a brand-new game he knows nothing about. Objective: to survive for six months.

From the master of alternate history comes an epic of the second Civil War.
