Yellow Moon by Jewell Parker Rhodes

Marie Laveau, wicked as a snake, strong as a bear.
Conjure woman, turn your life around. Upside down.
She'll put an evil spell on you.

Yellow Moon the third in Jewell's bestselling voodoo series has just published.A jazzman, a wharf worker, a prostitute, all murdered. Wrists punctured, their bodies impossibly drained of blood. What connects them? Why are they rising as ghosts?
Marie Levant, the great-great granddaughter of the Voodoo Queen, Marie Laveau, knows better than anyone New Orleans's brutal past -- the legacy of slavery, poverty, racism, and sexism -- and as a doctor at Charity Hospital's ER, she treats its current victims.
When she sleeps, she dreams of blood. Rain, never ending. The river is rising and the yellow moon warns of an ancient evil -- an African vampire -- wazimamoto -- a spirit created by colonial oppression.
The struggle becomes personal, as the wazimamoto is intent on destroying her and all the Laveau descendants. Marie fights to protect her daughter, lover, and herself from the wazimamoto's seductive assault on both body and spirit.
Echoing with the heartache and triumph of the African-American experience, the soulful rhythms of jazz, and the horrors of racial oppression, Yellow Moon gives us an unforgettable heroine -- sexy, vulnerable, and mysterious -- in Marie Levant, while it powerfully evokes a city on the brink of catastrophe.Yellow Moon is part two of the New Orleans trilogy that began with Voodoo Season -- magical realist fiction that takes the legend of the voodoo priestess Marie Laveau, as imagined by Jewell Parker Rhodes in the bestselling Voodoo Dreams, into the present day.

“...Rhodes puts...earnest thought into the [New Orlean's] dark history and comes up with a satisfying and eerie story that lies somewhere between the work of Anne Rice and James Lee Burke [...] The visceral descriptions of supernatural possessions are matched by equally vivacious sex scenes. A spooky, sexy novel about things that go bump in the night.”—Kirkus Reviews
“Fans of vampire and New Orleans horror will find this an unexpected and thought-provoking treat.”—Booklist
