Rear Admiral James Tecumseh barely survived his last mission against the Alliance of Free Stars with his reputation and life intact. Under a cloud of suspicion, he has been assigned to a quiet sector far from the front of the Terran Commonwealth’s war with the Castle Federation and its allies.

But when the Federation’s Operation Medusa cripples his nation’s communications and plummets an interstellar empire into silence, Admiral Tecumseh finds himself thrust into command of an entire fleet—and responsible for the safety of billions of innocent souls.

Enemies internal and external alike challenge the nation he is sworn to serve. Duty and honor call him to action to protect the innocent, and the Admiral and his new fleet are called to war once more.

But the darkest treason lurks where no one expects it…

Their enemies have friends at every turn, neutral worlds who will give them shelter—and if the UPA breaches that neutrality, everything Henry and Sylvia have worked for could crash down in flames.

If the UPA is to keep the peace in the stars of a fallen empire, their diplomats must be untouchable, their honor unblemished. But as Henry’s superiors prepare for all-out war, his ships fly ever closer to a deadly trap laid by an enemy that knows them all too well…
