The thrilling conclusion to the Half-Life Empire trilogy pits freedom fighter Kita against traitors, gangs, and the lasting chill of the Forever Winter.

Hacker and freedom fighter Kita Yamasaki has a new world to build. The granddaughter of Benjamin Yamasaki, a scientist and ambassador striving to make peace with the invading alien Teth, Kita was raised in the Forever Winter, a freezing, gray post-nuclear wasteland where humankind's last survivors dodge the murderous alien Vay and ally with the Teth, who arrived on Earth with the A-tech now critical to survival.

Accompanied by her lover, Bishop; her adopted daughter, Crouton; and Brecht and Vega, a human and Teth who spent their lives locked in an underground facility before meeting her, Kita has a vision for a better future, and it begins with Sanctuary, a lush safe zone where humanity can regain its dignity and safety. But the Iron-Blooded, a cult of alien-worshippers who swear allegiance to the Vay in exchange for their lives, are out for her hide.

Little do they know Kita possesses three Teth eggs, the spawn of three different castes, suspended in cryostasis gel, just waiting for the right opportunity to awaken—and she's pregnant. Can she help create a new civilization that won't end up like the ruthless Ex Cathedra or the isolationist United California? And can she protect the people in her care? Does the answer lie in the power armor waiting for her to step into it and fight?
