Based on a true story, this is the tale of two male penguins who raise a chick together. The message of the book is that having two daddies is just the same as having a mother-father family. Some may find this controversial, and it is recommended to those who find it difficult to accept love in all its forms, that they avoid this. Others have looked at this literally as about only animals in nature to skirt around the main topic, but like many other children's books, the characters are just humans wrapped in another package. This is about accepting differences, and more children should read books like this, although this should always be done with careful explanation by the parents on such social/cultural topics. As for the story itself, it is cute, yet simple, and has a central theme of family.
