Jacques Mouton was living a life of adventure as a buccaneer, plundering the Spanish Main until he made the fateful mistake of stealing Victor Orloff's bloodstone ring. Victor takes a shine to Jacques and initiates him into the brotherhood as he had done for many others over hundreds of years. He instructs him and his fellow initiates in their new lives. In present day New Orleans, Claire Corot, mourning a failed romance, comes out of her shell during Mardi Gras where she is swept off her feet by the dashing Jack Lamb. The joy and revelry of Mardi Gras in New Orleans plays itself out in Claire and her ribald friend and companion, Jenna Chandler. Falco, Diva, Patrick, Sarah and Sonny are back in Detroit plying the psychic trade Falco so deftly created. Lieutenant Kowalski employs Falco to help him confront a new threat to the city: The Beast, who is growing a vampire army that threatens to overwhelm not only the city, but the entire northeast. Falco and Sarah take on multiple jobs, rescuing many innocents while consuming their criminal assailants. Claire Corot's parents hire Falco to learn the fate of their daughter, who disappeared at Mardi Gras. He travels to New Orleans to discover her fate. Both he and Diva come under the assault of Camille Leveque, a Voodoo Priestess of the first rank who has history with Mama Midnight. Before all is done an unbelievably wicked business is uncovered and challenged. Powerful magic is employed. Ghosts come to life. Zombies rise from the grave. Those controlled by Voodoo spells refuse to die. The pirates of old ply their trade once again. Two old adversaries face off in a duel of magic. Falco's quest takes him deep into the Carribean Sea to face a skilled and powerful enemy who has no compunction about using the instruments of death and destruction he had been bequeathed. At the center of it all is the secret of the Mirrored Room, a place where one who knows how can project power anywhere in the world; the ability to be there, yet not there. Falco and his companions get to know the charm, the hedonism, the rot, the corruption, the history and the danger of New Orleans, the most haunted city in the Western Hemisphere.
