After a successful initial tour as a Marine rifleman, Lance Corporal Gracie Medicine Crow volunteers to become a scout-sniper, one of the deadliest - and most dangerous - military specialties in the United Federation Marine Corps. Gracie comes from the Apsáalooke Nation, a people with a long history of military tradition. Small in stature and considered stunningly beautiful, she is often underestimated, but that merely drives her to be the best sniper in the Corps.

United Federation Marine Lance Corporal Tamara Veal catches the attention of recruiters who nominate her to serve as a Single Combat Specialist. Gladiators, as they are better known, are genetically modified human champions who meet Klethos d'relle in the combat ring when the Klethos issue a challenge for a human world. Win, and the planet stays in human possession; lose, and not only do they lose their lives, but the world as well.

Convicted of a minor traffic violation, Rev Pelletier is conscripted into the Perseus Union Marine Corps...for up to a 30-year term of service. Anxious to get back to his civilian life and job, Rev opts for a shorter term as a Marine Raider taking the fight to the enemy. But with extremely high mortality rates, can he and his friends survive until their term of service is over? 

Ryck Lysander has proven himself as a Marine, as a warrior. As he is promoted to sergeant, though, his responsibilities expand beyond merely fighting to leading other Marines into battle. When an old ally becomes a new enemy, one well-equipped and trained, Ryck is pushed to his very limits as he tries to keep his Marines alive while fulfilling his mission of defeating the enemy on the field of battle.

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.

As a certified Federation "hero," Sergeant Ryck Lysander is offered a commission as a second lieutenant. Only, he doesn't feel like a hero, and his tendency to jump into a fight himself is at odds with his mission as a junior office. Accepting his commission might have been a big mistake. When contact with an alien species is finally made, that contact is not peaceful, and Ryck is thrust back into combat, combat that does not end well and plunges Ryck into an emotional crisis.

Major General Lysander has spent 38 years of his life dedicated to the Corps and sworn to perform the duties assigned to him by the Federation. In the process, he has become the most decorated Marine in its history. Ryck is faced with a situation that so horrifies him that he cannot accept it. Can he just stand by and let it proceed, or will he become an oathbreaker and put not only his life, but more importantly, that of his family, his fellow Marines and sailors, and the citizens of the Federation in peril?

As a captain, Ryck Lysander is given one of the most sought-after billets in the marines: an infantry company commander. His new battalion commanding officer, however, is not impressed with Ryck's past accomplishments, and Ryck finds himself struggling to fulfill the CO's expectations. Used to his "hero" status within the corps, his new position of having to prove himself grates on him. Now, as his company marches to the sound of gunfire, Ryck must find it within himself to be an effective combat commander.

As a sci-fi author with a hit TV show, I have a few ideas about what alien invaders are supposed to look like. In my stories, they’re technologically advanced monsters, with tentacles, and no faces. Turns out I was right about the technology. And about how angry they’d be. But the way they look is more terrifying than even I could have imagined. They look exactly like us. Because they are us.

A marine major is one of the orphan ranks, too senior to command a line company, but too junior to command a battalion. Newly promoted to major, Ryck reports for duty as the assistant naval attaché to the Confederation of Free States, the same government whose troops he'd recently fought in the Telchines. Ryck isn't happy about the assignment, but he buckles down for a long and boring tour of duty. But action seems to follow Ryck, and this is no exception.

Earth is in turmoil. The enemy is bearing down on us with every warship they have, and our only allies are in chaos. Our one hope for survival is Andy Clanton - a hack science fiction writer trying to convince some aliens that humans are worth saving. It’s an uphill battle, because to the aliens, we are the monsters. We look just like their sworn enemies, the Tevynians, who’ve sworn to wipe out both our civilizations. When everything falls apart and the fate of the galaxy is on the line, can Andy Clanton pull our fat out of the fire?

When leading archeologist Dr. Hank Murphy discovers an alien artifact on the Moon, corporate interests are quick to get involved. Murphy just wants to understand what this thing is and how it works. After months of research, he finally manages to locate the power source. The gate is soon activated...and Murphy is pulled through. Moments later, he finds himself in a war-torn corner of the galaxy where strangers like him are called Orphans...and they are considered extremely dangerous. Somehow altered by the experience, the archeologist now has enhanced strength, speed, and agility.

Jasper van Ruiker is an elderly algae farmer, drafted into the local militia to defend his village from the invading Tenners. Lieutenant Castor "Mountie" Klocek is a Navy pilot, shot down during an air-to-ground mission. Lance Corporal Javier Julio Gregory Portillo and Sergeant Gary Go are Marine combat engineers, the only survivors of a deep-recon mission to destroy a bridge.

Esther Lysander, the driven, professional Marine ever-conscious of the heavy weight of her father's legacy, is selected to become an officer. She has high goals for her career - very high goals - and she believes the best method to achieve success is to be a complete hard-ass, keeping emotions at bay. This outlook has resulted in some notable achievements, but at the cost of friends and her relationship with her twin brother Noah, a price she is willing to pay.

I thought the hard part of helping the Helta defeat the rampaging Tevynians would be the fighting. How wrong I was. To the Helta, we Earthers look just like the Tevynians, their mortal enemies. And convincing their government to ally with humans may be even beyond the crew of the starship James Bowie. But the clock is ticking, because the Tevynian fleet is bearing down on the Helta homeworld. If we can’t talk the Helta into accepting our help to fight them off, then Helta Prime will fall.... And Earth will be next.
