<p>The acclaimed best-selling author - winner of the PEN/Faulkner Award and the Orange Prize - tells the enthralling story of how an unexpected romantic encounter irrevocably changes two families' lives. </p> <p>One Sunday afternoon in Southern California, Bert Cousins shows up at Franny Keating's christening party uninvited. Before evening falls, he has kissed Franny's mother, Beverly - thus setting in motion the dissolution of their marriages and the joining of two families. </p> <p>Spanning five decades, <i>Commonwealth</i> explores how this chance encounter reverberates through the lives of the four parents and six children involved. Spending summers together in Virginia, the Keating and Cousins children forge a lasting bond that is based on a shared disillusionment with their parents and the strange and genuine affection that grows up between them. </p> <p>When, in her 20s, Franny begins an affair with the legendary author Leon Posen and tells him about her family, the story of her siblings is no longer hers to control. Their childhood becomes the basis for his wildly successful book, ultimately forcing them to come to terms with their losses, their guilt, and the deeply loyal connection they feel for one another. </p> <p>Told with equal measures of humor and heartbreak, <i>Commonwealth</i> is a meditation on inspiration, interpretation, and the ownership of stories. It is a brilliant and tender tale of the far-reaching ties of love and responsibility that bind us together. </p>
