With the short, brutal struggle between humans and insectoids ending in an apparent truce, the navy orders forces withdrawn beyond the Roach Frontier, hoping to avoid a destructive war against their new rivals.But when an ambitious human settlement and a colony of semi-feral insectoids clash in the Segovia System, the conflict quickly spirals out of control, with humans launching an invasion of mechanized troops, and insectoids responding with a rapid military buildup that threatens to push the war into an uncontrollable spiral of complete genocide.
