Evie wanted to escape from the deadly fangs of her relatives and for this, she takes the help of the most notorious man present in London. The name of the devil which Lisa Kleypas has selected for this story is Sebastian. Sebastian is a man who can seduce any woman in the city and he has a reputation for sleeping with multiple girls in the town.
When he puts his eyes on Evie, he thinks that he needs her in his bed but the girl is not that easy to get. She marries Sebastian to save herself from the relatives who want to make her their slave but she does not allow her husband to make a permanent relationship with her. Rather she asks her husband if he can have her in bed if he can celibate for three months.
Perhaps this was the toughest thing for Sebastian who has lived a life of leisure and sex throughout. Still, the man wants to prove his worth in front of his wife because he wants to keep this relationship as a permanent one. In the meantime, he also realizes that the danger of the past has not left Evie and there are forces that are coming to get her.
Sebastian is not ready to lose his precious wife so he decides to stand for her against the odds that dare to cross the line. Mary Jane Wells narrated Sebastian as a playboy at the start and then the character is given the voice of a hero at the climax. Marrying Winterborne talks about marriage issues and Devil in Spring can also be taken as a story in the same pattern. These stories tell about different problems that can appear in the path of true love.
