Desperate to escape her controlling family, Chloe Bradford scrambles up to the housetop of her Texas home on Christmas Eve. There she discovers a sexy stranger cloaked in shadow. He convinces her to shed her good-girl image and give into her most secret desires. The man's low, raspy voice tugs at her memory as much as it awakens her passion. Is he a Christmas miracle, or some figment of her imagination? When he tries to leave, she follows him, eager to learn his identity.

Zach can't stop thinking about Chloe, or their reunion on the roof. His wolf-half urges him to reveal his identity and claim her, but he doesn't dare. For both their sakes, he must remain in the shadows until he can control his inner beast's bursts of rage. After a decade of struggle he thought he could handle his curse, but Chloe's presence causes his control to slip. As the moon-rages become more frequent, he knows he's slipping toward the insanity that claims many of his kind. Only Chloe can save him, but he broke her heart over a decade ago. Her forgiveness would be the real Christmas miracle.
