Life without suffering is nearly unheard of for anyone. That pain caused Maybelle's fear of being bound by heartbreak using her need for independence to hold it at bay. Betrayals pain locked Edward's heart where love cannot find it. Intervention by their family, friends and desires passions drives them together. So what if society's conventions are flaunted, after all in the mores of nobility rules only matter if you get caught breaking them and even then forgiveness is just a matter of time and panache.
I love this; after all what better way to get away with breaking the rules than to live vicariously in a good book.
