Eden’s Legions by Peter Andra

Earth has been destroyed, but that was a very long time ago. This new galaxy, rich in habitable planets and life, is starting to feel like home. Yet the human presence is not welcome but tolerated as none of the galaxy’s other intelligent species has the strength to stop the human plague. It is their natural talent for war that makes humans so feared. Yet even humans tire of war and so have allowed the galaxy to enjoy a time of peace and their own colonies to grow and prosper. But behind curtains of peace an ambitious human general consolidates her power.
While the general endures peace, politics fail and weaken humanity’s once united cause. Sensing weakness, the general wakes her armies from decades of hypersleep. She will need all her strength and cunning, for the species she hopes to conquer is the most dangerous of them all, her own kind. Her conquest is promised in blood and fire, that is until the small scavenging crew of the Missing Madam intrudes on her cruel design. Not on purpose, of course.
