This is a really good overview of Las 21 Divisiones, which is Haitian Vodou's sister tradition in the Dominican Republic. Papa Hector is a friend of our Haitian Vodou house, and he is knowledgeable about both traditions on a very deep level. Before reading this book, I knew that our two traditions were similar, but Papa Hector's writing revealed to me that there are also some pretty significant differences between the traditions. For example, in Haitian Vodou we don't have much of an emphasis on Taino spirits, and we serve the Petwo lwa on a regular basis (whereas many 21 Divisiones houses will not). Overall a great overview of a religion that has had significant influence on Dominican culture and daily life.
