She and Channing have been secretly carrying on a fling for months, but everything’s about to change. And boy does Santa have his work cut out for him…
Channing Dawson has life just the way he likes it. His business is thriving. And he and Sadie have a no-strings “friendlationship”. What more could a man want? After his brother passed away, he didn’t dare risk loving and losing again. Yet, his heart is speaking a different holiday tune.
Sadie pulls a fast one and makes him her husband. A marriage of convenience or not, the rules are all blurred. He isn’t sure about having a holiday bride, until he realizes he’s had feelings for her all along. Sometimes the risk is worth it all. He could get used to sharing Christmas with her, but does she feel the same? Her secrets, and she has plenty, might ruin any chance they have for a future.
Then he receives the unexpected gift of a lifetime…
