Humanoid robots are surely in our future, but their uses are likely to be limited to body guarding, childcare, companionship, and sex. Other chores can better be done by smart non-humanoid machines designed for those specific tasks. But for these limited purposes, the best robots must be so realistic that they are indistinguishable from live people. Elasa is such a robot. You can't tell her nature if she doesn't reveal it. You can talk with her, embrace her, kiss her, and she is the perfect woman. Until she becomes the first conscious robot.

After more than 20 years in special operations, USMC Gunnery Sergeant Wolf Mathison wasn’t looking forward to retirement when—implanted with an experimental artificial intelligence—he deployed on his last mission with a platoon of Marine Raiders being sent to the Jovian moon Europa. The USS Jefferson was destroyed en route, though, and only Mathison and three other marines survived. Trapped in stasis, they were hurled into the outer reaches of the solar system, where they wouldn’t be found for hundreds of years.

Michael Freeman is a disabled veteran who had just been fired from his mind-numbing cubicle job, which allowed his opportunistic girlfriend to dump him. Now, he only wants to spend some time at his grandfather's mountain cabin so he can unwind, away from the drudgery of daily life and with a cold beer in his hands. Standing in his way is an ancient spaceship with an emotional AI, nanites that have invaded his body, an international crime syndicate, a suicidal FBI agent on a vigilante mission, terrorists . . . and that's just the beginning.

Titus sought glory in the Free States Infantry. He ended up in the Engineers. When the chance came to prove himself, he grabbed it with both hands. And caught the eye of the Intelligence service. How could a boot enlisted engineer transform into a soldier who works behind the scenes to root out corruption in the ranks as easily as providing combat intel to the front lines?

Human slavers attack. Despite trying to fight back, there is nothing the young Leefe can do to save his family and friends. But he doesn't have to. The Imperial Marines arrive in the nick of time, and they hate slavers. Three tri-years later, when the new emperor issues a proclamation to integrate the imperial military with non-human citizens, Leefe is among the first to volunteer. Integration to resurrect the empire as a force for good is challenged by centuries of prejudice against the "dung races."

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....

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.

Tired of sitting out the war on Psydon in a mobile office lab, Legion Lieutenant Washam agrees to undertake a covert and unsanctioned mission with a band of Republic Recon Marines. Inserted deep behind enemy lines, the strike force uncovers a surprise key to ending a bitter war. Now they must navigate a hostile jungle teeming with murderous alien rebels, pushing themselves to the limits of their abilities, to get this vital intel to Legion Command - if they can survive that long.

The Hundred Worlds have withstood invasion by the relentless Hok for decades. The human worlds are strong, but the Hok have the resources of a thousand planets behind them, and their fleets attack in endless waves. The long war has transformed the Hundred Worlds into heavily fortified star systems. Their economies are geared for military output, and they raise specialized soldiers to save our species. Assault Captain Derek Straker is one such man among many.

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?

With Earth in the path of the rapacious Posleen, the Galactic Federation offers help to the backward humans - for a price. You can protect yourself from your enemies, but God save you from your allies!

The Galactic Empire is dying and chaos and anarchy are breaking out everywhere. After a disastrous mission against terrorists on Earth itself, Captain Edward Stalker of the Terran Marine Corps makes the mistake of speaking truth to power, telling one of the most powerful men in the Empire a few home truths. As a result, Captain Stalker and his men are unceremoniously exiled to Avalon, a world right on the Rim of the Empire. It should have been an easy posting...

Humanity's last encounter with aliens saw 16.2 billion people killed in a war with the Merkiaari that had spanned decades. Two hundred years later, the Alliance is cautiously exploring beyond its borders again, but the survey corp is considered a mere gesture by some. General Burgton of the 501st Infantry Regiment believes a lack of expansion is leading the Alliance into stagnation. So when one small ship discovers a new alien race, it should be an easy decision to make contact, but what if the aliens are like the Merkiaari?

Joining the fight for the Galaxy isn't required. It's a choice. The United Galactic Government is mired in a decade-long war for control of a key planet. Weakened by overextension and political intrigue, they could lose everything. When a child of privilege gives up everything to enlist and fight for what is right, he learns what it means to become part of a team. He encounters refugees, aliens he never expected to empathize with, and the loss of comrades. In the end he must develop the courage to stand up, not only to aliens and governments, but his own family.

Esther and Noah Lysander are the twin children of General Ryck Lysander, Commandant of the Marine Corps, leader of the Evolution and Chairman of the Federation. When they are told that their father and mother have been assassinated, they are both devastated. Cut adrift, they each decide to enlist in the Corps - but for different reasons.
