Former Marine Jason McKay thinks his first assignment as a Military Intelligence officer—as the head of a protection detail for a Republic Senator’s daughter on her humanitarian mission to the star colonies—will be a boring waste of time. Until Aphrodite, the agricultural colony they’re touring, is invaded by an inhuman enemy that may threaten Earth, and McKay and his people are trapped far behind enemy lines. Separated from his team during the attack, McKay has to try to keep Valerie O’Keefe, the idealistic daughter of a powerful politician, alive in the face of threats from an alien menace and a more mundane revolutionary front that is working to free the forced exiles from their servitude to the MultiCorps that run the colonies. Meanwhile, McKay’s second in command, Shannon Stark, leads the remainder of the special operations unit in an effort to sabotage the invaders in their effort to loot the resources of Aphrodite and to learn more about their true identity. Together, these two officers fight to survive, to protect the civilians in their charge… and to do their duty

Honor Bound returns to the star-spanning human Republic of Duty, Honor, Planet five years after the attempted invasion of Earth by General Antonov’s Protectorate and their biomech army. The invasion was defeated, but in the aftermath, the Republic economy has collapsed, and President Jameson is defeated in the next election by former Senator Daniel O’Keefe. After O’Keefe ends the former practice of allowing developing nations to dump their political and economic undesirables onto the star colonies, where they serve as cheap labor for the mines run by the monopolistic Multicorps, unrest begins to build in those nations and in the Colonial Guard military that represents them. The Multicorps are unhappy as well and pressure the government to allow them to produce biomechs of their own to replace the forced emigrants as a source for inexpensive labor. Rumors begin to spread of a mutiny by the Colonial Guard in the colonies and of a possible assasination attempt or even a coup against the O’Keefe administration on Earth. Amidst this turmoil, reports come in of a military outpost on the fringes of Republic space that has been completely wiped out, and all signs point to a return of General Antonov’s Protectorate from wherever they’ve been hiding the last five years. Jason McKay, now head of Spacefleet Intelligence, takes a star cruiser to investigate, while Shannon Stark, his second in command, sends an agent in undercover to investigate the rumored coup. What they each find, light years away from each other, might mean that the two threats faced by the Republic government are not at all unrelated…
