Many millennia ago, the human race was enslaved by the An - a fearsome alien people whose cruel empire once spanned the galaxies, until they were defeated and consigned to oblivion. But a research mission to the planet Ishtar has made a terrifying - and fatal - discovery: The Ahanu, ancestors of the former masters, live on, far from the reach of Earth - born weapons and technology ... and tens of thousands of captive human souls still bow to their iron will.

In the final days of World War II, the Allies ransacked Berlin. Third Reich scientists were highly sought-out prizes for Americans and Russians desperate to possess Nazi nuclear knowledge. But they failed to capture one of the most vital members of Adolf Hitler’s inner circle, Hans Kammler, a liaison with the Nazis’ silent partners whose technological wonders nearly helped the Axis win the war - the alien species the Germans called the Eidechse. More than seven decades later, US Navy SEAL Mark Hunter witnesses the impossible in North Korea....

The Year is 2040. The Marines have landed on Mars to guard the unearthed secrets of an ancient and dangerous alien race: Ourselves. Scientists have discovered something astonishing in the subterranean ruins of a sprawling Martian city: startling evidence of an alternative history that threatens to split humanity into opposing factions and plunge the Earth into chaos and war.

Chaos has erupted throughout the known galaxy, threatening countless colonies and orbital habitats - as the Associative struggles vainly to keep the peace. Extreme measures are called for in these times of dire crisis, and the Star Marines are awakened from their voluntary 850-year cybe-hibe sleep. But General Trevor Garroway and his warriors are about to discover that the old rules of engagement have drastically changed.

The year is 2162. Thirty-eight years after first contact, Lord Commander Grayson St. Clair leads the Tellus Ad Astra on an unprecedented expedition to the Galactic Core, carrying more than a million scientists, diplomats, soldiers, and AIs. Despite his reservations about their alien hosts, St. Clair is deeply committed to his people - especially after they're sucked into a black hole and spat out four billion years in the future. Civilizations have risen and fallen. The Andromeda Galaxy is drifting into the Milky Way. And Earth is most certainly a distant memory.

Terminal Lance Lucky Lee Savage likes his life. Sure, doing PT hungover is a pain, but no one can dodge responsibility like he can - or sweet-talk the cooks into giving out double rations.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

Aliens exist...and, as it turns out, most of them aren’t that friendly. Jacob Brown wasn’t even born yet the first time they attacked Earth. He was only 14 the second time it happened. When Earth finally came together and fielded its first spaceborne military, Jacob didn’t hesitate to volunteer. Serving aboard a mighty starship, he’d be able to defend his planet - and his family - when, inevitably, they came again.

Get ready to experience two more origin stories in the Backyard Starship universe.

Out of the blue, a young Space Fleet officer's dream becomes reality: He's made captain of a starship. Just in time for the return of humanity's most terrible enemy, after 50 years of peace. To survive against this enemy, Captain Tad Thatcher will have to do more than learn how to become an effective commander, or how to wrangle his wayward crew. He will need to reinvent space combat. From scratch.

There he was in his sailboat in the middle of the Atlantic, all alone and loving it. Well, there was a US Navy carrier group on his southern horizon, but he was a Navy guy himself, so he didn't mind. Then came the UFOs, hurtling in from the Outer Black to overfly the carriers at Mach 17. Their impossible aerobatics were bad enough—but then they started shooting at each other, and at the Navy, with nukes. Little ones at first, but winding up with a 500 megatonner at 90 miles that fried every piece of electronics within line-of-sight.

Geary believed in the Alliance. Even when he uncovered overwhelming evidence that the highest echelons of the government and fleet command were involved in secret programs and prison camps, he believed it was worth saving. He believed his duty was to see that justice was served even though some factions feared that revealing the truth would cause the Alliance to crumble. But after narrowly surviving two assassination attempts when he brings evidence of the misdeeds to the capital star system, Geary realizes that some want to get rid of him.

It should be a simple, stress free assignment - but things rarely work out as they should.

Earth in 2064 is politically corrupt and in economic decline. The Long Depression has dragged on for 56 years, and the Bureau of Sustainable Research is hard at work making sure no new technologies disrupt the planned economy. Ten years ago, a band of malcontents, dreamers, and libertarian radicals bolted privately developed antigravity drives onto rusty seagoing cargo ships, loaded them to the gills with 20th-century tunnel-boring machines and earthmoving equipment, and set sail - for the moon.

The Majority always gets what it wants. Thomas Hill just wishes it didn't want him. There's no way to escape a galactic mob of mind readers, no way for him to blend in with his foster family and other average Americans. Because Thomas invented a way to save his own life. His custom medicine halts the progress of his degenerative neuromuscular disease. Newscasters proclaim him the next Einstein, but mere humans have no idea his bioengineered processing capacity rivals that of a supercomputer. They just think he's smart. However, there are other bioengineered supergeniuses in the Majority.

The starship Freedom was once a mighty warship. Today, she's a tourist attraction. The space wars ended long ago. The Freedom is now a flying museum; the tourists love it.

He was a real soldier once, back when the Freedom was a real warship. He never imagined himself running a tourist trap. Right after Christmas, he plans to retire. Then, on Christmas day, the aliens attack.

Since time immemorial, they have been on course for Andromeda, the neighboring galaxy of the Milky Way. This is the prophecy of the ancients, the one goal that unites them all, their cult. But then the unthinkable happens: the journey stops because the planet enters the orbit of a mysterious object that can't be seen in any telescope.
