The Magical Worlds of Harry Potter: A Treasury of Myths, Legends, and Fascinating Facts - David Colbert Interesting, if simplistic, insight into the various myths, legends and languages used as reference by JK Rowling in the Harry Potter series. The writing style is obviously aimed at a younger audience (tween to younger teen), but the research is solid. I like that I was able to get my hands on the expanded version, but it's a little annoying that the main text covers books 1-5, while books 6 and 7 are sort of tacked on at the end. I wish some of the chapters, like the one on the use of Latin for spell names had been expanded to include spells from books 6 and 7 (not that you can't figure out the Latin roots, but it's a nice little place for a quick reference). This book is best utilized as a reference guide, although you can read it straight through like I did and still enjoy it. Enjoyable and worth the $4 I spent on it at the used book store.
