I looked at this book today and thought, I'm almost halfway through - I don't really care what happens. I very rarely give up on a book but I lost complete interest in this one.
A middleaged woman, suffering from empty nest syndrome - a bored husband. Who in their right mind would believe their husband when he says he wants you to have an affair and wants to know the details - does that sound like a situation that would end well? I didn't care what happened to their marriage, or the characters themselves.
Life's too short to spend on this kind of rubbish.
