Not a bad idea, that of schooling unadapted husbands, but that's probably the only positive thing I can mention about the book.
The epic thread is average and just ok, the characters are the ones which do the damage: linear, artificial and dull.
Simon, the rich guy, has nor manners neither brain, as he doesn't love Sophie but acts as she's the only one available woman on the planet. Mark, the childish father, resigns as a sign that he cares about his wife (My God, if stupidity hurts...), Sophie isn't the cleverest girl I've seen, not to speak about her dear mother. Even the child, the little Arthur, is regarded as a nuisance, and that's quite a pity. No empathy, no high marks...
