Earth Fleet: Rebel Fleet, Book 4 / B. V. Larson

At long last, Earth has a handful of starships. Surrounded by Rebel Kher, Imperials, and the mysterious Nomads, humanity dares to assert our right to independence.  

The interstellar community reacts harshly. In the eyes of our neighbors, we're upstarts, dangerous beings who don't know our place.   

For the Kher, freedom can only be won through battle. War fleets arrive to instruct us, and Captain Leo Blake is again sent out to voyage among hostile stars.   

We're far from ready, but the time has come. It's game on.
