Gabe Mercer and Danielle Prescott have been together since high school. Staying together has meant compromise and experimentation. Having an open relationship is working well for them.

But when Dani's secret fears get the best of her and Gabe springs a surprise, the holiday countdown starts to feel endless. Will trying monogamy be the end of their relationship?
