The Orion Plague: Alien Invasion #3 (Plague Wars Series Book 8);

Guns blazing, Master Sergeant Jill Repeth and her team search the nuclear wasteland for her kidnapped fiancé, while Spooky Nguyen prepares Earth's first-ever Space Marines for duty aboard the experimental battleship Orion. But even commanded by the legendary Navy Captain Henrich Absen, Orion is hopelessly outclassed, and only by supreme sacrifice can Earth be saved.

For now, that is -- because the Destroyer is on its way.
