This conclusion of the Hyperion saga (Hyperion, Fall of Hyperion, and Endymion) finds Raul Endymion, Aenea, and M. Bettik still on the run from agents of both the Pax and the TechnoCore. But Aenea is reaching maturity, clearly growing into the messiah who will one day bring down the church and stop "the resurrection." One answer lies in Aenea's blood, which she shares with her followers through a ritual of communion; the blood allows anyone to travel through the Void Which Binds, but it cannot coexist with the cruciform that brings immortality. And although Aenea's gift makes her both a power and a danger, she is also a young woman, vulnerable to the forces allied against her.
