Newbery Honor–winning author Patricia Reilly Giff tells a vivid, contemporary story about a remarkable boy who risks everything for his family and a bold girl who helps him. At home in Mexico, Mateo knows where he belongs: with Mami, Abuelita, little brother Lucas, and big brother Julian. When Julian leaves to work in el Norte, the United States, Mateo misses him. And when the family stops hearing from Julian, Mateo knows he has to find his beloved brother. With only his old notebook and a backpack, Mateo heads for the border, where dangers await: robbers, and the border police, who will send him back home or perhaps even put him in prison. On his journey, Mateo meets Angel, a smart, mysterious girl who can guide his crossing. Angel is tough; so is Mateo, and his memories of his loving family sustain him. Because no matter what happens, he can’t go home until he finds Julian.
