Continuing directly from Hyperion, the second Cantos novel resolves the pilgrims' fates as interstellar war erupts and the true nature of the TechnoCore—the artificial intelligences secretly governing human civilization—is revealed. Told partly through the dreams of a John Keats cybrid, the novel is simultaneously a war epic, a philosophical meditation, and an emotionally crushing conclusion to the tales begun in the first book. Astonishing in scope and ambition.
