When she steps into the carriage that is to take her on her wedding tour, Elizabeth Darcy is the happiest woman alive - until she sees the look of torment on Mr Darcy's face and discovers that he has a deep, dark secret that nearly destroys their love, their marriage and even her very life. Darcy, it turns out, is a vampire, and so is the rest of his family. They cannot be outside during sunrise or sunset. Lady Catherine, naturally, is at the source of this misery, having turned Georgiana into an undying friend for her vampire daughter, Anne, and then Darcy as the perfect mate for Anne. Now Lizzy and Darcy must travel across the Continent all the way to the Pyrenees to find a way to break the Darcy curse. But Lady Catherine won't give up her undead without a fight, and Lizzy both will be tested to the limits of their endurance and love if they are to save themselves, and each other.
