Imagine that your husband wrote you a letter, to be opened after his death. Imagine, too, that the letter contains his deepest, darkest secret, something with the potential to destroy not just the life you built together, but the lives of others as well. Imagine, then, that you stumble across that letter while your husband is still very much alive. Cecilia Fitzpatrick has achieved it all; she is an incredibly successful businesswoman, 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, and not just for her: Rachel and Tess barely know Cecilia or each other, but they too are about to feel the earth-shattering repercussions of her husband's secret.
Discovering a tattered letter that says she is to open it only in the event of her husband's death, Cecelia, a successful family woman, is unable to resist reading the letter and discovers a secret that shatters her life and the lives of two other women.
