Having a retold folktale that specifically names the culture/people it is taking the tale from easily allows anyone reading to find the source material, but it's not always easy for an outsider to see the problems in a retelling. Thank goodness for Debbie Reese. Check out her posts on McDermott's Arrow to the Sun and it's problems here.
I really liked the imagery in the book. The illustrations are very striking, but there are many problems with the story (like the fact that McDermott straight made up a ceremonial dance).
