Five years after physicist Mark Holder discovered the Slipstream Drive in 2058, humanity reached for the stars and began to colonize the galaxy. For centuries, humans continued to populate system after system without encountering intelligent alien life. Some 1,200 years later, after many generations of relative peace, in the year 3278, human space is invaded by a powerful and mysterious enemy. To these invaders, the very concept of free will is heresy. Their crusade—to eradicate humanity. The war begins, and the fight for the survival of the human race is on.

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.

Commander Dalton Reeves is a maverick officer with exceptional genetic strength and a dark family history—a history that will come back to haunt him. Punished for exceeding orders one time too many, he’s packed off to the "The Abyss"—the most dangerous space station in the galaxy. But a posting that should have led to five years in obscurity will propel Reeves into the center of an interstellar war against a long-forgotten alien adversary with a bitter grudge. 

Commander David Bryce is scheduled to lead a routine re-supply run for the Orbital Development Group (ORB) to the fledgling colony on Mars. Without warning, he’s taken away by government agents and told the mission parameters have changed. They’ve discovered something. And it’s drifting closer to Earth. Atlas Donovan tirelessly hunts for an artifact, and tracks the piece to Lake Como, Italy. After the recent news from ORB, Atlas is more drawn to the trail than ever. 

Opportunities there are few and far between…that is unless you're willing to put on a uniform. For ace-pilot Deborah Allen Riker (a.k.a “Admiral Dare”), life had never been easy. She's defended Earth against countless enemies, both alien and human alike. Now a civilian and academic living on the fringes of civilized space, she has committed herself to a life of solitude and studying a race of long-dead aliens. Everything was great…until she finds herself dragged into a new conflict. A conflict she never saw coming.
