In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

For Hayden Cross, a military investigator in the far future, whether his wife faked her death is the question that is probably going to get him killed. Having lost the only job that kept him sane, he has few resources and fewer leads. Oh, and a sadistic crime lord really wants to kill him. As he fights through an underworld of fanatical rebels, callous bounty hunters, and corrupt cops, each step takes him closer to the truth about his wife’s fate and the oppressive government he once loyally served. On the way, he may even stop a war...but only if he betrays everyone he loves.

In the wilds of a jungle planet, the Legion fights in brutal combat as Republic marines fly their SLICS from one tragedy to the next. H292, a repurposed warbot, shows the heart of a hero as he wades into the battle not to destroy - but to save.

A company of Army Rangers is sent on an interstellar colony ship to secure a foothold on a dangerous, alien planet through violence of action. Leaving behind a warring Earth flung headfirst into a conflict of mutual assured destruction, the Rangers and the accompanying crew of first colonists are guided on a 40-year journey by an unprecedented artificial intelligence. But when they emerge from the frigid embrace of cryosleep, they awake to a nightmare, finding themselves greeted by the same ruthless enemy that brought about the ruin of Earth.

More than two centuries after World War III poisoned the planet, the final bastion of humanity lives on massive airships circling the globe in search of a habitable area to call home. Aging and outdated, most of the ships plummeted back to Earth long ago. The only thing keeping the two surviving lifeboats in the sky are Hell Divers - men and women who risk their lives by skydiving to the surface to scavenge for parts the ships desperately need.

Idealistic Navy Lieutenant Jacob Grimm just wanted to honor his mother’s sacrifice in the last great war. When he’s forced to return fire and destroy a squadron of ships to save his own, he thinks he’s the hero...until they discover the ships are full of children. Disgraced and denied promotion, Jacob’s career is over. That is until the head of ONI needs a disposable officer to command a battered destroyer on the rim.

Two civilizations clash. A rebellion grows. The fate of the galaxy hangs in the balance. Technical Chief "Pappy" Gunther is a grizzled, burning-out commando in the United Earth Armed Forces. He ponders a return to civilian life, yet feels a strong sense of belonging to his elite team. When colonists on a far-flung world request aid, a task force from several allied systems is assembled. Pappy and his crack unit are sent to investigate and to engage a mysterious alien force from beyond.

After discovering a cache of Prothean technology on Mars in 2148, humanity is spreading to the stars---the newest interstellar species, struggling to carve out its place in the greater galactic community. On the edge of colonized space, ship commander and Alliance war hero David Anderson investigates the remains of a top secret military research station---smoking ruins littered with bodies and unanswered questions. Who attacked this post, and for what purpose?

Five years ago, the US Space Force became a reality. And while those writing the checks took things very seriously, the other military branches did not. As a result, Space Force was populated by undesirables. My name is Captain Ethan Stone, a decorated member of SEAL Team Six turned Space Force "recruit". Flash forward five years and between tenses. President West is in office. Power has shifted. And Space Force is defunded. With just a handful of us still living on base, we find ourselves being evicted. But before all of us can leave, aliens invade.

The human race is all but extinct after a war with Partials - engineered organic beings identical to humans - has decimated the population. Reduced to only tens of thousands by RM, a weaponized virus to which only a fraction of humanity is immune, the survivors in North America have huddled together on Long Island while the Partials have mysteriously retreated. The threat of the Partials is still imminent, but, worse, no baby has been born immune to RM in more than a decade. Our time is running out.

I Am Number Four: The Lost Files: Secret Histories is the second collection of action-packed novellas from Pittacus Lore. Initially published separately as digital originals, these three stories are now together in one volume.

The world had become used to the metahumans - people sometimes perfectly ordinary, but sometimes quite extraordinary in appearance - who mostly worked with their governments as high-powered peace officers, fighting crime, and sometimes fighting rogue metahumans who had become super-criminals. Then that comfortable world ended in just one terrifying day.

Sheriff Hayden Duke was born on the Pilgrim, and he expects to die on the Pilgrim, like his father, and his father before him. That's the way things are on a generation starship centuries from home. He's never questioned it. Never thought about it. And why bother? Access points to the ship's controls are sealed, the systems that guide her automated and out of reach. It isn't perfect, but he has all he needs to be content. Until a malfunction forces his engineer wife to the edge of the habitable zone to inspect the damage.

Captain Mitchell "Ares" Williams is a space marine and the hero of the Battle for Liberty whose shot heard 'round the universe saved the planet from a nearly unstoppable war machine. He's handsome, charismatic, and the perfect poster boy to help the military drive enlistment. Pulled from the war and thrown into the spotlight, he's as efficient at charming the media and bedding beautiful celebrities as he was at shooting down enemy starfighters.

Benjamin Carter Mason died last night. Maybe he threw himself off a bridge into Los Angeles Harbor, or maybe he burned to death in a house fire in San Pedro; it doesn't really matter. Today, Mason's starting a new life. He's back in boot camp, training for the only war left that matters a damn.
