Merritt Alder is done with Earth. The planet is polluted and overpopulated, and its people are hungry. Earth's first colony, Galena, is a pioneer world 10,000 light years away. It has clean air, unpolluted water, and continents of arable land. Anyone can start a new life…if they can get there. For Merritt, the journey is only the beginning. Obstacles arise every step of the way, forcing compromise and sacrifice. And not everyone on his ship is pure of heart. The bonds he forges on the journey will be the key to surviving on another world—a world anyone has yet to fully explore.

The totalitarian East has triumphed in a massive invasion, and the United States has fallen to a dictatorial superpower bent on total domination. That power is consolidating its grip through concentration camps, police state tactics, and a total monopoly upon the very thoughts of the conquered populace. A tiny enclave of scientists and soldiers survives, unbeknownst to America’s new rulers. It’s six against six million - but those six happen to include a scientific genius, a master of subterfuge and disguise who learned his trade as a lawyer-turned-hobo, and a tough-minded commander....

Nora Devi is a xeno-archaeologist with a complicated past. She has buried more secrets than she’s dug up. Widowed in the recently ended twelve year war between Capitoline and Palantine, she now makes a living as an independent tagger in border space. Captain Liam Kimani could be credited with ending the latest royal war. Instead, he’s blamed for it. Dirty commoners aren’t meant to lay their hands on royalty. He has no regrets.

Two hundred years ago, aliens invaded Earth. A violent war followed. The enemy won. Some of us escaped, most of us didn’t. On Proxima they flourished - the invasion forgotten. On Earth we floundered - the horror began. Their world is advanced, peaceful, and secure. Our world is broken, savage, and overrun. A new invasion is coming. A hunger that has swallowed half the universe. They don’t care which planet we live on. They want to end us all. But where there is life, there is hope. And where there is hope, there are heroes. This time, vengeance will be ours.

What comes after boarding school for an evil lord? The military academy, of course!

Will the Guide succeed? And will Liam ever notice that the Guide isn't actually trying to help?

The first interstellar war, a generation ago, left humanity enslaved. Now humans fight in the armies of their masters to save themselves from annihilation. At least, that's what the propaganda insists is true. What the layers of lies keep hidden is how badly the new war is going for the people of earth. Now it's Dylan Kane's turn to blast into the heavens and join the battle, but what his masters don't know is that by putting a weapon in his hands, they're giving him the key to unlocking his hopes of freedom.

In the not-too-distant future, a 21-member crew launches from Earth. Their mission: to establish a temporary colony on Mars. Little do they know that colony will become permanent–and the last stand of the human race. Because, without warning, every single person left on Earth simply...vanishes. Now, a thousand years later, the resources needed to sustain life are running out, and the very existence of the Mars colony is threatened. Humankind has only one option–to return to its home planet.

Joe Colsco boarded a flight from San Francisco to Chicago to attend a national chemistry meeting. He would never set foot on Earth again. On planet Anyar, Joe is found unconscious on a beach of a large island inhabited by humans where the level of technology is similar to Earth circa 1700. He awakes amid strangers speaking an unintelligible language and struggles to accept losing his previous life and finding a place in a society with different customs, needing a way to support himself and not knowing a single soul.

In war, there is no second place. To ensure victory, planetary governments employ private armies to help fight their battles. And the Berserkers are the best. As the galaxy's preeminent mercenary force, they are hired by governments and corporations to do jobs that are too tough, too messy, or too deadly for their own forces. Expertly trained and equipped with the most advanced weaponry, they are willing to do whatever it takes to fulfill a contract - if the price is right.

Two hundred years ago, a fleet of colony ships left Earth and started a settlement on Proxima Centauri. Centurion Space Force pilot Nathan Stacker didn't expect to return home to find his wife dead. He didn't expect the murderer to look just like him, and he definitely didn't expect to be the one to take the blame. But his wife had control of a powerful secret. A secret that stretches across the light years between two worlds and could lead to the end of both. Now that secret is in Nathan's hands, and he's about to make the most desperate evasive maneuver of his life.

Calamity is loose, and it's been busy learning—from its time with Netty to running wild among the stars, the ultimate evil seeks nothing less than complete dominion over all space and time. And for Calamity, life is in the way.

Earth Government turned soldiers into cyborgs to terraform Mars. After a decade of hard, lonely work they are little more than the machines as which they are treated—until the arrival of female settlers awakens feelings they have almost forgotten....

After the mysterious disappearance of several Rebel transport ships, Luke, Leia, and R2-D2 journey across the galaxy in hopes of discovering the fate of the missing ships.

What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed that it did - and in doing so, put at risk everything we know about the fundamental laws of the universe. Leonard Susskind and Gerard 't Hooft realized the threat and responded with a counterattack that changed the course of physics.

The starship Earthling, filled with thousands of hibernating colonists en route to a new world at Tau Ceti, is stranded beyond the solar system when the ship's three organic mental cores—disembodied human brains that control the vessel's functions—go insane. The emergency skeleton crew sees only one chance for survival: build an artificial consciousness in the Earthling's primary computer that can guide them to their destination—and hope it doesn't destroy the human race.

The enigmatic Investigator Mossa follows his trail to Valdegeld, home to the colony’s erudite university―and Mossa’s former girlfriend, a scholar of Earth’s pre-collapse ecosystems. Pleiti has dedicated her research and her career to aiding the larger effort towards a possible return to Earth. When Mossa unexpectedly arrives and requests Pleiti’s assistance in her latest investigation, the two of them embark on a twisting path in which the future of life on Earth is at stake.
