From the cover copy of The Serpent and the Rainbow:
Drawn into a netherworld or rituals and celebrations, Davis penetrated the vodoun mystique deeply enough to place zombification in its proper context within vodoun culture.
In other words, the Rational Masculine West encountered the Mystical Feminine Other, and then had sex with it.
I haven’t tried to read the book itself, so I don’t know if this is the fault of the marketing department or Wade Davis. But jeebus. It’s like a whole game of Colonialism Bingo, all in one sentence.
