Can the star-faring nations of the Known Galaxy stop the million-year-old force gathering at their doorstep? Hasty alliances are formed and former enemies stand together as the US Navy, weakened after the Horde invasion, must rebuild in the brief months before it has to fight for the survival of humanity. Always FaithfulWhile America prepares for war, the conflict’s outcome may depend on a single person. Colonel Lisbeth Zhang, USWMC, has been captured by a cult of warp-crazed cultist and is held in a fortress planet deep in a lawless part of the galaxy. A joint team of Marine Wraiths and CIA agents led by Heather McClintock launch a covert rescue mission. Zhang’s warp abilities may be the key to defeating the Nemeses – but only if the small team of Marines can defeat impossible odds to bring her back alive.
