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. By the time Martha finds out what is wrong, it doesn't really matter anymore. It is too late to get the only thing she has ever wanted. Or maybe it will turn out that you can stop loving someone and start again from nothing - if you can find something else to want.
