Publisher's Summary

An empire broken by hubris. An officer raised by chance. Oaths that must be honored. Oaths that must be betrayed.

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....

Great start on a new series .

It’s so enjoyable at times to luck into the start of a series that you’re going to end up waiting with anticipation for the next audiobook . I’ve found myself listening to some of the first series I purchased when audible first arrived . Books I had read a very long time ago . Thank you podium audio for the military sci-fi I enjoy .

Great sequel

I’ve been wanting a sequel to the castle federation books for YEARS. This was great to see how the alliances strike affects the commonwealth. I’d give this more stars if they’d allow it. The ending totally threw me! If you liked the castle federation books you will LOVE this one. Can’t wait for book 2.

James Tecumseh was one of my favorite characters in the the Castle Federation series.
This was everything I could have wanted in a continuation of his story. Please write more now!!!
