i was concerned at first that Visions of the Cailleach was an attempt to appropriate the Celtic goddess for general use in magic (a fear born of my experiences with faddish ignorant americans) but I was pleasantly surprised. this book reads like a lit review, so not only did it greatly add to my to-reads but it also attempted synthesis based on primary and secondary sources rather than convenience. great coverage of the whole Celtic world (ó Chataibh go Ciarrí and beyond) and an admirable appreciation for folk belief also contribute to making this a wonderful read for anyone interested in the Celtic worldview.
