Comfort and Joy by Kristin Hannah (2005)

A Christmas miracle novel. The novels I have read by Hannah so far have taken someone with a major life crisis and works them through to a level of healing. Here Joy is still reeling from a divorce and spontaneously gets on a plane to just get away for a while during the holidays, but the small plane crashes. She walks away from the wreck and walks into the life of 10 year old Bobby, who is suffering from the loss of his mother. His divorced father Daniel has returned to take care of him and get the bed and breakfast ready to sell, but they do not get along. Joy helps to heal the relationship, falling in love with both boy and father. But things are never what they seem to be...
