Deep in the bayous of Louisiana exists a world of fortune-tellers, soothsayers, and makers of potent elixirs. Among them is Evangeline’s grandmother, Louise, a master of scent-making and perfume. And when Eva is eighteen, Louise leaves her the ultimate gift --- a scent created just for her. However, the bottle comes with a warning: do not remove the crystal stopper unless you want everything in your life to change. 
 
From the moment she places a drop on her neck, Eva is the object of intense desire to everyone around her. Strangers follow her down the street, a young boy appears at her door asking for a favor, and two men --- one kind and good, the other dark and exciting --- fall madly in love with her. As her greatest gift becomes an unbearable curse, Eva will be forced to wonder if it is possible to truly love someone evil and to question the true nature of her grandmother’s legacy.
