Lady Rosella Prescott has loved one man for as long as she can remember. To her dismay, he has only ever seen her as a friend?or worse, as a little sister. Despite her best efforts to capture his attention, nothing seems to change. It frustrates her endlessly, and at times she wonders if she's a hellion for her boldness. But in her heart, she knows she's his hellion. If only he would look at her and truly see it.

Lucian Abbot, the Marquess of Kistleton, has desired Rosella ever since he realized she was no longer a girl, but a desirable woman. How could he act on such feelings when she is the sister of his closest friend? The impropriety of it haunts him, and he suppresses his desire. That is, until one fateful night when his resolve shatters, and he can no longer ignore what has been in front of him all along.

With the magic of Christmas in the air and a shared wish for love, Rosella and Lucian are drawn together at last. But as the night ends, they must confront a difficult choice: to follow their hearts or honor their loyalties.
