Exhibit A: My love of all things Welsh.
Exhibit B: My obsession with faeries, fairy tales, and folklore in general.
Exhibit C: The title of this book.
The defense rests.
More seriously, this is a fantastic collection. There's a wide variety of fairy tales in it--mostly featuring actual faeries--and I felt that it gave me a really good feeling for Welsh folklore in 1907 (when the book was first compiled). One can't really judge on the literary merit of folktales, but they're well-told, and most are entertaining and intriguing. A few had unexpected similarities to folktales of other cultures that I've encountered, and I would be interested to find out where these tropes originated (if it can be pinned down) and how they passed from one to the other.
