Grimm. (2012). "The Three Black Princesses." Grimm's Complete Fairy Tales. New York: Fall River Press.

This fairytale is about an enemy in East India that would not retire until he was given $600. There also once was a poor fisherman and his son. The fisherman gave his son away for $600, and his son became the burgomaster. However, his son escaped. Three princesses in black were sent to the fisherman. He didn't even recognize his sons, but he wanted to thank the three princesses. He turned the princesses half white, but this angered the princesses because they were looking for their three brothers of seven chains who were buried under the castle.
This fairytale was confusing for me to read even, so I am not sure how I would use this in the classroom yet. I still need to think this fairytale over.
