Imagine your husband wrote you a letter, to be opened after his death. Imagine, too, that the letter contains his deepest, darkest secret -- something so terrible it would destroy not just the life you built together, but the lives of others too. Imagine, then, that you stumble across that letter while your husband is still very much alive. Cecilia Fitzpatrick has achieved it all -- she's an incredibly successful business woman, a pillar of her small community and a devoted wife and mother. Her life is as orderly and spotless as her home. But that letter is about to change everything, both for her and for two other women she barely knows.
