i could not help but believe that deirdre mayfair would be happy if she could read such a history , if she could know that her daughter was so deeply admired and so uniformly successful , and i vowed to myself that i would never do anything to disturb the happiness or the peace of mind of rowan mayfair - that if the mayfair history , as we knew it and understood it , was coming to an end in the liberated figure of rowan , then we could only be glad for rowan , and could do nothing to affect that history in any way .
