This came really close to fulfilling all my criteria for a folktale collection. It certainly fulfills the primary one: an abundance of good stories. In addition, this has variety, especially cultural variety, and the stories told are told well. It certainly fulfills its mission of providing stories in which women center prominently, and those women are infinite in their characteristics.
There were, however, a couple of things I did not like. First, for a collection that exceeds most others of its kind in the geographic diversity of the stories' origins, it includes only one story from all of South America. Surely an entire continent with hundreds of distinct cultures isn't devoid of heroines?* While Ragan does acknowledge the collection's lack of South American folktales in her introduction, and while interest in South American folktales has grown immensely since Fearless Girls was published (therefore increasing supply), it's still disappointing.
Secondly, I was surprised to find two stories attributed to the "People of the Northwest Coast" were actually Frankensteins written by Christie Harris, a white anthropologist. Harris mashed together material from several different tribes and changed the vocabulary of the stories, calling chief's daughters "princesses." I spend probably more time than is healthy worrying about the tension between cultural appropriation and exchange in my amateur study of folklore, and I'm not going to argue whether or not Harris should have created these stories, but I am going to definitively say that they are no longer Native stories and should not be included as such. At least those two stories served as a reminder to take the rest of the collection with a grain of salt, as other stories were almost undoubtedly altered in more insidious ways through translation or during collection.
And lastly, Ragan's notes at the end of each tale got on my nerves. They're her personal reflections, and didn't add anything to my appreciation of the stories. I stopped reading them in fairly short order (though they did provide the information about Christie Harris, so I suppose they weren't completely useless).
For all of that, I still recommend it. It's big, including over a hundred stories, and a lot of those are excellent. Also, as annoying as Ragan's annotations are, the actual endnotes are fairly good. At the bare minimum, they provide the source of each story, and some include additional information on how the tale was originally collected or some cultural context. Always appreciated.
