Infidelity... cheating... secret lovers... I have to say I enjoyed this book very much. It is beautifully written and does not insult one's intelligence or criticize, it only informs on what the etiquette should be in the matter. Your opinions on the morality of cheating may be against this sort of thing. I believe in a general sense I would say that I think it is wrong. However, that does not change the fact that it happens and to have some general guidelines on how one should behave is really very useful. I highly recommend this book.
