The Serpent and the Rainbow: A Harvard Scientist's Astonishing Journey into the Secret Societies of Haitian Voodoo, Zombis, and Magic by Wade Davis

Wade Davis is one of the persons I really admire. He dedicated an important part of his life to anthropology and ethnobotany, so he is one of the persons who tried it all from the herbalist point of view.. :) up-to meeting the most interesting and remote communities of people.

In this book, Davis relates his stay in Haiti, a place and culture that he felt in love with.
His story presents the mind-set of the local people. Through the eyes of the US PhD author, the voodoos are presented, very different from the Hollywood's portrait, with subtle and insight details of the zombies, their herbals, their secrets, and people way of thinking.
