Day of the Dead is a very important holiday in Latin America. It is sometimes incorrectly thought of as a morbid holiday, or a Mexican version of Halloween. While the word "dead" or "muertos" is in the name, this holiday is the way that the people of Mexico honor the lives of ancestors, celebrate the joy of life, and connect with their Mexican heritage. Young readers will enjoy the amazing, colorful photographs of the Day of the Dead celebration, and a supportive glossary helps expand their vocabularies along with their cultural awareness.
