The 18th Race Books in Order

After a spacefaring species destroys a human colony and nearly wipes out its investigators, a massive relief force heads toward Troy. The landing initially appears unopposed, but a devastating attack reveals how little humanity understands the enemy it has chosen to fight.

Human Marines on Troy struggle against repeated attacks by the birdlike Dusters while damaged ships send scattered reinforcements below. Plans for relief from Earth may come too late as a fresh alien fleet threatens both the defenders and their remaining naval support.

Human forces on Troy face renewed alien assaults in orbit and on the ground. A devastating armored weapon forces engineers to search for a weakness or a way to use it, while Earth’s leaders struggle to determine humanity’s next response.
