Haylee Tremayne is tired of the road. The concert tour for Three of Hearts was a success, but the puzzling tension between her bandmates, Ben and Lucas, is getting old. They all need some time off. Too bad it's Christmas...for Hayley, it's the most terrible time of the year.

But the day of their last concert, she discovers she's been dumped by her boyfriend for a sexy girly-girl. Story of her life—all guys ever see is tomboy Haylee. At the after-concert party, she drowns her sorrows and—desperate to feel feminine and desired for once in her life—asks Ben and Lucas for a threesome. And it's just as hot and sexy and fun as she'd hoped.

Back in Nashville, Ben and Lucas work on proving that one night wasn't a mistake, and it's amazing. But the strain between the two of them is mounting, while Haylee's own anxiety about Christmas continues to grow. The spirit of Christmas is supposed to be love, but as emotions run high and tension builds, they might be putting everything at risk...their band, their success, and worst of all...each other.
