Question: This is strictly a tourist rag. Don't waste your time. If your looking for a basic introduction to Voodoo, try Laennec Hurbon's Voodoo: Search for the Spirit; Voodoo & Hoodoo by Jim Haskins; Sallie Anne Glassman's Vodou Visions; Leah Gordon's Book of Vodou or even the Complete Idiots Guide to Voodoo.
