Book #12 in 2015

Heart of the Matter by Emily Giffin.

Dr. Nick Russo starts and affair with the mother of one of his pediatric patients.  Story is told from the POV of his wife, Tessa, and the other woman, Valerie.

The characters were well developed, but I didn't like any of them.  I was really disappointed because I normally enjoy the author's novels.

3 stars.
