I just finished reading A Stopover in Venice by Kathryn Walker. The story started out a bit slow, but grew more and more interesting the longer I read. A young woman is unhappy in her marriage with a famous musician. During a train ride with him and his entourage, she abruptly gets of the train in Venice and leaves him to travel on to his next show. Over the course of a month she has a great adventure in Venice and figures out what she wants to do with the rest of her life.
An interesting fact that I just learned today is that Kathryn Walker was once married to James Taylor and it is speculated that she based the husband's character on her own experiences with him.
