The Weekend — Peter Cameron

On a midsummer weekend, in a country house in upstate New York, three friends, Lyle, Marian, and John, gather on the anniversary of the death of John's brother, who was also Lyle's lover. As Tony's absence haunts each of them in different ways, the reunion is complicated by the presence of Lyle's new lover, a much younger man named Robert, and a faux-Italian dinner guest with a penchant for truth telling. As the seemingly idyllic weekend proceeds, each character is stripped bare, and old memories and new desires create a chemistry that will transform them all.
