How To Be Good — Nick Hornby

A wise and hilarious novel morality and what it means to be a "goof person" from the bestselling author of Dickens and Prince, Just Like you, Funny Girl and High Fidelity.

A brutally truthful, compassionate novel about the heart, mind, and soul of a woman who, confronted by her husband's sudden and extreme spiritual conversion, is forced to learn “how to be good” -- whatever that means, and for better or worse…

Katie Carr is a good person…sort of. For years her husband's been selfish, sarcastic, and underemployed. 

But now David's changed. He's become a good person, too -- really good. He's found a spiritual leader. He has become kind, soft-spoken, and earnest. Katie isn't sure if this is deeply felt conversion, a brain tumor -- or David's most brilliantly vicious manipulation yet. Because she's finding it more and more difficult to live with David -- and with herself.
