Christmas comes but once a year—unless you’re Natalie Miller.

Torn between two different ambitions, Natalie flips a coin to help her decide which life she wants, but then can’t bring herself to look at the result. The next thing she knows, she’s living every December day twice. At first, the holiday do-over seems like a gift. She has the chance to learn from her mistakes and avoid pitfalls. Things get more complicated as her two lives diverge.

In one life, she gets to work on a glamorous account and spend a lot of one-on-one time with a handsome executive—but she has to give up one of her dreams. In another life, her job is in jeopardy and she has to deal with a grouchy client—but she’s doing things that matter to her, and that client has hidden depths.

As Christmas Eve approaches, the double life grows more and more challenging. Will Natalie be able to break the spell and land in the right life—and with the right man—for good?
