A chance encounter with Zeet of The Accord almost doomed our galaxy in " Tears of Gallia." Dave Brewster travels to a forgotten planet to uncover their intentions. The cyborgs of The Accord were once human but have long ago moved their brains into robots. Now their leaders are massive constructed planets, hosting millions of smaller cyborgs and billions of human slaves who serve as laborers and food.
But The Accord has a problem. The Magallenic Clouds are running out of metal to build more robots. Now they must invade our galaxy to recruit new Friends and to harvest the metal and feedstock of our worlds.
While the Free Society masses its starship fleet to fight back, Dave must find a way to slow them down or somehow convince them to end their heinous reign of terror. The Accord is an epic tale of impending war against a vastly superior enemy. It is also a story of new love, enduring faith, and the ultimate power in the universe.
