As war rages on across the galaxy, a diplomatic mission turns into a desperate fight for survival.

Captain Peter Fromm: He and his Warp Marines face old enemies and new threats inside a colossal space habitat ruled by a mysterious alien civilization. Their lives and the fate of their country hang in the balance.
Heather McClintock: The CIA operative must prevail against her toughest opponents yet: a race of decadent immortals with godlike powers and murderous urges. Her only weapon is an untried new technology with lethal side effects.
Major Lisbeth Zhang: The fighter pilot risks her very soul when she makes contact with entities from the depths of warp space. Her choices may lead humanity towards a golden age – or eternal damnation.
Corporal Russell Edison: Russell just wanted to travel across the galaxy, meet exotic aliens, and shoot them. These new ETs want to play with Charlie Company, and they are about to find out that Marines play to win.
