War of the Singularity — Al Stevens

The computer-governed Singularity to the north and the female-dominated Amazonia to the south are about to clash in a war in which neither side knows of the other. The Singularity's mainframe launches an invasion to confiscate electricity-generating resources, and Amazonia is unprepared.
Slaves of both civilizations, androids and clones, are caught in the middle. Rebellion arises when Verdun, an enslaved laborer, and JCNSA-27, a condemned android, form an alliance. The outcome can only be freedom or annihilation.
