Many of her novels are set in Ireland, dealing with the tensions between urban and rural life, the contrasts between England and Ireland, and the dramatic changes in Ireland between World War II and the present day. Her novel Circle of Friends was made into a 1995 Hollywood movie starring Chris O'Donnell and Minnie Driver with a radical change of ending.
Binchy announced in 2000 that she would not be going on tours with any more novels, but would be devoting her time to other activities, and to her English-born husband, Gordon Snell, a children's author. However, she has written three further novels since then - Quentins, Night of Rain and Stars and Whitethorn Woods.
