The best!

Devil in Winter - Lisa Kleypas

I love Evie. She sounds, at first, like the most boring of the wallflowers but really she is the strongest and most determine girl. And Sebastian is the most infuriating, arrogant, wonderful man you will ever have the misfortune to love. I love every second of this book. 

I supposed the reason why I loved it so much is because it played on the fantasy of having a man love you so much and so desperately that they will change their ways just to be with you. Also, I felt that the relationship between Evie and Sebastian was well flesh out and that they understood one another.
