The book is about a young family from a small town in Mexico and their experiences crossing the border to America. Their trips across the border are scary and harrowing. It gave us empathy for these immigrants, whether they come illegally or not. They face dangers in the crossing and in living here, and they were just trying to find a better life. While we don't think people should be allowed to come here illegally, we still need to see them as people, not aliens, and try to find a better way to work things out.
