The story is told through the eyes of Rene a perfumer living in 1533, in the court of Catherine de Medici. As well as the life of a woman living in modern times Jac. Jac is a TV shows celebrity that focuses on mythology; she also has skills as a perfumer, which is the family trade. She is brought to France to care for her sick brother, Robbie, while in France Jac is left to take up where Robbie left off. I liked this book, it has some slow parts to it, but over all I really liked this book. It was lacking in suspense and at the end, I figured out some of the mystery before the book was over. The use of past and present works in this book, it is written from first person point of view in the past, and third person point of view in the present. This works it flowed well, and made it so that the reader knows what time period they are reading in. The idea of soul mates is well executed in this book, as well as the relationship of Jac and her brother.
