Voodoo and Afro-Caribbean Paganism is an excellent book on all aspects of the various Afro-Diasporic religions in the Americas. The author, Lilith Dorsey, has been a Voodoo priestess for decades and has researched all the different varieties: Voodoo, Voudoun, Santeria/Lacumi, Condomble, Obeah, Umbanda, Hoodoo, etc.
This book was originally meant to be part of a series of “concise guides,” along with what eventually became Bonewits’s Essential Guide to Witchcraft and Wicca, Bonewits’s Essential Guide to Druidism, and Diana Paxson’s Essential Asatru. All of the books were meant to follow a similar pattern, with sections on the Paleopagan, Mesopagan, and Neopagan versions (as appropriate) of each pantheon/path, as well as discussions of beliefs, practices, rituals, and dangerous phonies to watch out for. Both books do an excellent job of separating fact from fiction and of dispelling racist nonsense about the two paths.
I encouraged the writing of Lilith’s and Diana’s books, sold them to the publisher, and happily wrote a foreword for each. If you have a serious interest in West African/Afro-American or Northern European Paganism, I highly recommend both these titles.
