Echo the Mystical Cave Spirit (Hardcover) (ISBN-13: 9780228896050)

Some adventurous children are not afraid to explore on their own, but they sometimes go astray and need someone to come to their rescue. Help can come from not only adults but also unexpected sources, such as animals and unexplained supernatural intercession. Cautioning children to stay near their group while playing and being aware of their surroundings teaches safety and self-reliance.
