The rhyming text, the unique Wangdoos and their yak, and the overall not-too-preachy message about teamwork make this a great story for children ages 5-8. It also has a rhythmic pace with repetitive phrasing making it a great read-a-loud for family story time. As I read it, I read it out loud so that I could enjoy the sounds. Also the yak mascot is an adorable surprise. (Advance Reading Copy provided by LibraryThing Early Reviewers)
