A practitioner of Vodou must test the boundaries of her powers to solve a ritual murder in New Orleans and protect everything she holds sacred. Haitian-American Vodou priestess Mambo Reina Dumond runs a healing practice from her New Orleans home. Gifted with water magic since she was a child, Reina is devoted to the benevolent traditions of her ancestors. After a ritual slaying in the French Quarter, police arrest a fellow vodouisant. Detective Roman Frost, Reina’s ex-boyfriend—a fierce nonbeliever—is eager to tie the crime, and half a dozen others, to the Vodou practitioners of New Orleans. Reina resolves to find the real killer and defend the Vodou practice and customs, but the motives behind the murder are deeper and darker than she imagines. As Reina delves into the city’s shadows, she untangles more than just the truth behind a devious crime. It’s a conspiracy. As a killer wields dangerous magic to thwart Reina’s investigation, she must tap into the strength of her own power and faith to solve a mystery that threatens to destroy her entire way of life.
