Long ago, the first reign of Grigori Geist nearly destroyed the Earth.

Returned from exile, Geist is secretly rebuilding his kingdom beneath Antarctica, assembling his robotic Vaucan race to war against mankind. Only one obstacle remains: the war hero known as Brian Renney.

Yet Brian is losing a battle against his fears. Scars of heart and mind linger from his days in Vietnam, fueling his failures as husband and father. This embitters his youngest son, Jason – a star athlete torn between pursuing the love of his life, and meeting the demands of a father who is far from the storied army captain he once was.

And all the while, Geist is coming for them.

In this dark hour, Brian and Jason encounter a war to end all others… and an unexpected ally who, once meant for evil, shall forever be a force for good.
