Joanna's Husband and David's Wife by Elizabeth Forsythe Hailey

He thought he could read her mind... until he read her diary.

David thought he knew Joanna. After twenty-five years, why wouldn't he? But when he finds the journals she's kept through their marriage, he discovers a woman with secrets... a woman he's losing--and only now does he discover why.

A profoundly intimate portrait in a time when the meaning of marriage has irrevocably changed for us all.
