Because there is so little available on this subject it was refreshing to see a book with this title.
The book begins with the fears of the husband that his wife is cuckolding him, and the realization that it is infact exactly what he wants. It gives a quite accurate account of the kinds of thoughts,fears, and doubts that such a relationship brings. For me however, I would have prefered the relationship between the husband and wife to be a little less "cold" and more of a shared loving ( although unusual ) thing.
definately worth a read if you are interested in this subject.
