Rain Player by David Wisniewski
We read this as part of our ancient American study of the Mayans. The boys really liked it. The illustrations are superb and bring a lot to the story. The story itself is sensational, as are most legends/fairy tales, but that's what makes it fun. As with all things Mayan, there are a lot of references to their gods.
Valuable addition to study for the Mayan culture. It makes it very easy for the little ones to feel involved too.
