French Quarter socialite Zéolie Cheval finds her father mysteriously and greusomely murdered in his bed by an unseen force that is now hunting Zéolie and everyone she loves. Plunging into an ever-tightening web of family secrets to solve the murder and protect her loved ones, Zéolie enlists help from a handsome police officer, Ursuline nuns, a Voodoo priestess, and her long-dead grandmother.

Will Zéolie stop the maniac, or die trying?
