Dependable Devyn Voss is no stranger to cleaning up her mother's messes, but this one's gone supernova. In search of love, her flighty mom has invited all of her exes to celebrate her Christmastime 50th birthday. Which is trouble enough, but only gets worse when Devyn's former stepbrother shows up to the party. His dark brown eyes and lazy smile still setting sparks off inside of Devyn that she's desperate to ignore.

Nashville songwriter Vaughn Taylor only came to the party to support his dad. And if he happens to see his pretty ex-stepsister there, that's just fine. But the minute he lays eyes on her, he's gripped by all his old desires—to undo all her uptight and get past that guarded exterior. They were never supposed to see each other again, but now that they have—all those sparks have become a bonfire. But will this little bit of Christmas crazy last... or will it end with the season?
