Hayden is not content to sit around and wait for a couple of lives until she can be with her true love . . . she plans to do something about it. What she does, is get herself hypnotized and transported into the body of one of her past lives, Catherine, Lady De Grey. It seems Catherine and her husband love each other but their marriage is cursed. Hayden is determined to find out why before time runs out for Catherine and Tavey, which is what is about to happen. Once again, she gets herself hypnotized and seems to dream of a different past life/relationship, that of Callie and Talis.
Deveraux also wrote a lot of identical twin heroes (because sequels) whose true love could be identified by her innate ability to tell one twin from the other. Feminist literary theorists could have a field day and a picnic lunch with this motif: Instead of the male gaze identifying or isolating the female, the female gaze differentiates the male, and in doing so, identifies herself.
