The Trellixian Empire was constantly expanding, seeking new worlds for its ever-increasing population. If worlds were discovered with existing sentient populations, they were cleansed to make room for colonization. Hundreds of budding civilizations had been eliminated by Trellixian battle fleets. On Earth, years in the past, a scout ship fleeing from the Trellixians crashed. Scientists investigating the wreckage discovered what the Trellixians had done to the world the scout ship escaped from. They also discovered it was only a matter of time before the Trellixians reached Earth.

The starship New Horizon is Earth's first attempt at an FTL capable spaceship. But others don't want the mission to succeed.

The Eternals have decided to conquer Originator space. All that stands between them are the Originator AIs and the Humans, or at least that is what the Eternals believe. In preparation for the invasion, they begin gathering their massive warfleet. Fleet Admiral Jeremy Strong sets out to rescue Grayseth deep in Eternal territory. The rescue mission will make him realize just how dangerous the Eternals are.

The cryosleep chambers are beginning to fail. Surveillance of Hocklyn space has revealed that the Hocklyns are thirty years ahead of their projected schedule and will soon reach human occupied space. War could break out any day if something isn't done. The human leaders suggest a daring plan to buy them the additional time they need to strengthen the Fleet, as well as the defenses protecting their worlds.

The Federation is pushing the Hocklyns steadily back, but they still vastly outnumber the humans and their allies by hundreds to one. Fleet Admiral Hedon Streth has to defeat them before they develop newer and more deadly weapons. In a bold move, Hedon comes up with a daring plan to attack the Hocklyn home worlds. If he succeeds, the war will be over. And if he fails then the Federation will face imminent defeat.
