Lady Rosella Prescott has loved one man her entire life. He has never seen her as anything but a friend, or worse a little sister. Nothing she does changes that, and she's tried everything. Which makes her think she's a hellion, and perhaps in some ways she is. But in her mind, she's his hellion. If only he would actually look at her to see it.

Lucian Abbot, the Marquess of Kistleton has desired Rosella since he first noticed she'd grown up. But how could he want his closest friend's sister with such scandalous intentions? He suppresses his feelings until one night he can no longer ignore what is in front of him.

The magic of Christmas, and a wish for love bring them together. At the end of one long night they have a decision to make: between love and loyalty.
