Siobhan Dunmoore

Captain Siobhan Dunmoore wanted to believe the long war against the invading Shrehari Empire had finally banished the ghosts of her past. But when her ship Iolanthe, a heavily armed man-of-war masked as a bulk freighter, finds itself in need of replenishment after a long patrol spent stalking human and alien foes, she is confronted with events eerily reminiscent of a past she thought buried.

A distress signal draws Siobhan Dunmoore's Q-ship Iolanthe, a battlecruiser disguised as a bulk freighter, away from her devastatingly successful hunt through Shrehari occupied space, plunging Dunmoore into a dark, merciless universe of competing government organizations, undercover warfare, and organized crime on a galactic scale.

Special Operations Command has assigned her to Task Force Luckner, whose mission is replicating Iolanthe's success on a larger scale. Unfortunately, neither her new superior, Rear Admiral Kell Petras, nor any other captain in the task force understands successful commerce raiding requires a different mindset. Instead of sheepdogs, they must become wolves in sheep's clothing, and Dunmoore is just the right officer to teach them. Yet Petras and his flag captain are not interested.

Life hasn't been easy for Siobhan Dunmoore and many of her fellow veterans since the Shrehari War ended. The Fleet's quick return to a mundane peacetime footing left them unmoored and incapable of fully readapting after years engulfed in an existential struggle. Meanwhile, the memories of all those hard-won lessons, paid for with humanity's dearest blood, are fading as careerists, bureaucrats, and politicians in uniform replace the leaders who brought about the war's end.

Yet her appointment to the headquarters of the Third Fleet, responsible for humanity's most restive frontier, is no accident. Things aren't quite right in what was once the most ferocious and effective formation in the Navy, and its control over the Rim Sector's outer edges is failing.
