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.
