The Ca'cadasan are no longer knocking at the door of the Empire, which doesn't mean they have forgotten the humans who have handed them the first defeat in the history of their Empire. The Cacas are learning from their mistakes, and are retooling their war machine in the face of their greatest opponent ever. The Ca'cadasan Emperor is not satisfied with the state of his military, and changes will be made. New technologies are in the forefront of his plans, and a major covert strike is planned against the humans. He plans for this to be the death stroke to the human Empire, the preliminary to his massive invasion, even as Sean works to defeat the coming invasion and launch a counter stroke to take the initiative. The Klavarta have the full attention of the Cacas on their front, and the Nation of New Earth is the target of a major offensive. This Great Admiral is smarter than most, and he has planned a trap to destroy the Klavarta fleet, rendering Sean's new allies impotent to continue the war. And the Fenri, all but defeated, unleash a weapon of terror on the New Terran Empire. Teams of raiders have entered Imperial space, mandated by their Emperor to destroy everything they come across. Liners, merchant ships, small warships, and even inhabited planets are targets, and the fleet must go on a search and destroy mission to seek out the raiders and stop them before millions fall to their weapons.
