After 10,000 years, he is returning home, hoping to fulfill his last desire. But ony if his catastrophic past can be forgiven Jack is barely human; just part of his organic brain remains protected and supported by his metaform body. He hopes for a peaceful end to his life, on Earth with his rejuvinated family, but Earth's managing AI has other intentions. With the aid or hinderance of Debois, the AI's slightly odd emissary, Jack will have to repair some of the damage he has caused over the millennia; he will have to locate and destroy the 7 copies of himself he created and hid to ensure the survival of his biological material.But he has to be quick; Number Seven is leaving the known universe at a significant proportion of light speed, Number Two is eating worlds, and Number Five is coming for him.
