Emma Shea Abernathy is fully aware of her social role: marry well, live extravagantly, and, most of all, exhibit perfection. And it started with saying "I do" to future governor Trent Broadway.

With her carefully crafted life in full swing, she knows she's made a big mistake. Leaving it all behind, she hides out at her great-grandmother's beach house in Crickley Creek. There, she discovers a secret room containing a well-preserved 1920s Prohibition speakeasy-and some surprising information about the women in her family. This leads to a new plan: to become a woman who acts contrary to what is expected. In other words, a Firefly Girl.

The problem is, no one else embraces her change of heart, especially her first love, Scruggs Willingham III. He still refuses to forgive her for marrying someone else. Despite the olive branches she extends throughout Crickley Creek, it appears she'll spend Christmas alone.

Until a rare Christmas snow brings the one miracle she needs: the freedom to accept herself.
