Mac and Edie Swan lead a picture-perfect life in Oak Hill, Alabama. Edie is a respected interior designer, Mac is a pediatrician, and they have two kids and a historic home on Linden Avenue. Life is good - mostly. Until a young woman walks into Mac's office one day. A young woman whose very existence threatens all Mac and Edie have built and all they think they know about each other. Nineteen years after a summer apart, the past that Mac and Edie thought they left behind has come back to greet them. As they wade through the upheaval in both their family and professional lives, they must each examine choices they made long ago and chart a new course for their future.
