Eddie Teach is a former Federation ace wasting away on the outer rim when General Lance Reynolds recruits him for a black-ops unit. Paired with the genetically-enhanced pilot Julianna Fregin and her electronic intelligence Pip, Eddie must build Ghost Squadron from scratch — a diverse team of humans and aliens armed with one of the most powerful Q-Ships in the fleet. Their mission: hunt down the Brotherhood, a faceless organization launching devastating attacks against Federation colonies.

Eddie Teach is a man who lost his direction after a decorated military career — self-reliant, wisecracking, and slow to trust but fiercely devoted once he does. Julianna Fregin is his equal and counterpart: disciplined, centuries-old, and determined to prove that genetically enhanced soldiers deserve more than footnotes in history. Together they are the heart of the Squadron.

Across seven books the team dismantles the Brotherhood, defeats the mastermind Felix Castile, then faces a new existential threat from shapeshifting aliens called the Saverus who wield a reality-tearing device called the Tangle Thief. The series balances rapid-fire military action with genuine character growth as Eddie and Julianna evolve from reluctant partners into co-leaders forged by shared sacrifice. Themes of loyalty, purpose, and what it means to belong run through every mission.
