The Half-Life Empire

Hacker Kita Yamasaki would do anything to escape the post-apocalyptic landscape that was the result of the Forever Winter. But for a normal person, the only options are the war-hungry nation-state of Ex Cathedra or the isolationist United California. Fortunately, Kita is anything but normal. When she finds a faded brochure for the BC Oasis—an underground greenhouse capable of sheltering a quarter million people—she jumps at the opportunity, even going so far as to steal a fission battery the oasis requires to operate at full capacity.

Hacker Kita Yamasaki is a survivor, a fighter, and the granddaughter of Dr. Benjamin Yamasaki. Once the sole human ambassador seeking peace with the alien Teth, now the doctor is long dead—and only Kita holds the knowledge that can save humanity. Though she's already foiled one effort to destroy Earth and forged an alliance with the violent, power-armored Judge Gascoigne, new threats arise. Namely, the Iron-Blooded cultists, who wish to ally themselves with the aliens in exchange for their own lives.

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.
