The Conquest Trilogy, Book One, The Quest For Freedom

Affer was once a peaceful planet, until a war broke out between its six inhabiting species. The humans, who were once the mightiest force on Affer, were massacred in droves, and the ones who survived the onslaught were reduced to mere slaves. The five other species divided the humans amongst themselves and returned to their respective kingdoms.

The years passed, turning into decades and centuries, without any change. Eventually, the humans had accepted their fate as slaves... all except one. Four hundred and seventy-three years later Fletcher Rush starts his journey to free his kind, and conquer the planet.
