A major theme in the book is people's hopes and dreams as sources of the motivation they need to succeed. Hope is each character's central motive for action. As Dolores tells her son, Juan, to return to Comala, she hopes that he will find his father and get what he deserves after all of these years. Despair is the other main theme in the novel. Each character's hopes lead to despair since none of their attempts to attain their goals are successful.
