Temptation at Twilight: Lords of Pleasure by Jo Carlisle
A fantasy resort that offers all the pleasures of life-and death...
Vampire brothers Aldric, Soren, and Luc Fontaine own and run La Petite Mort, an adult fantasy resort for the adventurous of heart-and body. Humans, shifters, Fae, and other beings gather to enjoy two weeks of fantasies-come-true at the New Orleans estate. The brothers themselves have experienced everything life, and death, have to offer...except finding their true mates.
Soren makes a bargain with a Voodoo Priestess, binding him to her forever in exchange for the return of the wife he lost a hundred years ago. He is soon convinced that one of the new guests is his wife reincarnated, and an intense sexual attraction turns to a true emotional bond...but all could be lost when the Priestess comes to collect.
