Immigration is one of the central themes of the novel. The four main characters have different reasons for leaving their homes, families, and friends, but they all essentially have the same conviction that Morocco is not a place where they can live comfortably, safely, and authentically. They do not leave everything behind because they have always dreamed of it, Lalami argues, and their decision is a last resort. They will risk a dangerous crossing, spend a great deal of money, and take a risk without a guaranteed payoff because the situation in Morocco is so dire for them.
