What does the opening epigraph by Yeats tell us about novel?

The epigraph from William Butler Yeats' poem "The Second Coming" sets the tone and provides insight into the themes of the novel. The poem speaks of a chaotic and violent world, where "the centre cannot hold" and "the falcon cannot hear the falconer." This suggests that the novel will explore themes of social and political upheaval, and the struggle for order in a world that is falling apart. The poem also hints at the idea of a cyclical nature of history, with periods of chaos and destruction giving way to new beginnings. This could foreshadow the events of the novel and the characters' journeys through a changing world.
