Spanning five decades, Commonwealth explores how a chance encounter reverberates through the lives of the four parents and six children involved. Spending summers together, 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. A brilliant tale of the far-reaching ties of love and responsibility that bind us together. By the winner of the PEN/Faulkner Award
