The war continues...and the body count rises. With humanity joining the alliance to fight the Naxli invaders, the war should be turning in their favor. Unfortunately, the enemy must not have gotten that memo. Across the galaxy, the Naxli strive for total domination. To create a stronger resistance, Gunny Pelletier is sent to work with the various races, but he and his team soon discover that reaching common ground and coordinating military action is far more difficult than they’d imagined. But the Naxli aren’t pausing to give the allied races time to work out the kinks, which means it's time for humanity to go at it alone once again. Bureaucracy must wait while Marines do what Marines do best. Besides, humanity owes the Naxli a few paybacks, even if the rest of the allied races are not willing to join the mission.
