Home World — Michael W. Davis

Derek Fagan suffers the misery, the horror and pain of living as a non-classed citizen of Home World until he's indentured to serve as a warrior of the Tellurian Entente, tyrannical rulers of Earthcom. His choice? Exercise their oppressive authority at the cost of his own morality, or return to the nothingness existence of a Null in the ghetto zone. Two wars, a conflict to quench colonial rebellion, and a tour to subjugate his own kind accumulate more darkness than he can endure.

Derek loses everything after one desperate act to end his turmoil, until providence steps in and offers a different path on a hellish planet outside the control of his masters.
