On the heels of their Caldecott Medal-winning Smoky Night, Eve Bunting and David Diaz have created a dazzling new picture book that glows with holiday joy and the spirit of Mexico. Carlos and his family are going home for Christmas-across the border from California to Mexico. Mama and Papa are excited, but Carlos and his sisters are not so sure. To them, California is home now, even though they were born in Mexico. But as the family drives to their hometown through festive villages and sun-kissed landscapes, Carlos and his sisters discover there's magic in their roots and that-whether in Mexico or California-home is where the heart is: with one's family.
