Sorrow and Bliss

This novel is about a woman called Martha. She knows there is something wrong with her but she doesn't know what it is. Her husband Patrick thinks she is fine. He says everyone has something, the thing is just to keep going.

Martha told Patrick before they got married that she didn't want to have children. He said he didn't mind either way because he has loved her since he was fourteen and making her happy is all that matters, although he does not seem able to do it.
