Peace is a novel by Gene Wolfe that explores the nature of memory. Our narrator, Alden Dennis Weer, goes over memories from different parts of his life—his childhood, early adulthood, middle age, old age.
As in many of Wolfe's novels, much of the novel is taken up with stories within stories—stories told to Weer, particularly stories told to his the child Weer.
Different critics interpret what is actually happening in the novel differently. One interpretation is that Weer is dead, and the scattered memories are those of a ghost. Another interpretation is that the memories of his old age are the fantasies of a middle-aged Weer, who is experiencing a nervous breakdown.
Wolfe has described Peace as his favorite work, as it is the one where he came closest to achieving his original goal.
