I enjoyed this Magic Tree House companion book, and even though it is written for elementary school students, I still learned some things from it. The book begins with some general information about Irish folklore. Then, in addition to leprechauns, the book briefly discusses clurichauns, fear deargs, banshees, pookas, dullahans, merrows, grogochs, ballybogs, and trooping fairies. The book is illustrated with appealing black-and-white pictures and a number of black-and-white photographs. It also includes an index and a bibliography of books, videos, and websites.
