It is 1964: Bert Cousins, shows up at Franny Keating's christening uninvited, where he notices a heart-stoppingly beautiful woman. When Bert kisses Beverly Keating, his host's wife, he sets in motion the joining of two families. In 1988, Franny Keating, now twenty-four, meets one of her idols, the famous author Leon Posen.
After telling him about her family, she unwittingly relinquishes control over their story. Franny never dreams that the consequences of this encounter will extend into the lives of her scattered siblings and parents.
