"A bokor serves the loa with two hands, one for good and one for evil." Far away in the Caribbean, a witch doctor quietly brews his evil magic until a devastating earthquake uproots him and sends him north. Armed with rituals, herbal concoctions, and trances, the Bokor brings his version of Vodun to Seattle. Siri Thorson, graduate student in anthropology and avowed atheist, scoffs at the supernatural before she discovers blood sacrifices in her neighbors' yard and attracts the Bokor's thirst for vengeance. He terrorizes her by day and invades her dreams at night. An old friend offers temporary relief when he invites her to the exotic city of Salvador, Brazil. In the romantic, tropical atmosphere, Siri finds love and a culture she never imagined. When she encounters the ancient Afro-Brazilian religion of Candomble, she discovers the answer to her problem back in Seattle. She must accept the existence of the supernatural to battle the Bokor on his own turf--the world of ancestral spirits and angry, African gods.
