When a stranger crashes Hart Granger's 50th birthday party, the shock sends him reeling. Not only is this man from Vermont Hart's half-brother - the child their mother put up for adoption before she was married - he's also the bizarre incarnation of a lie Hart told his little sister when they were kids. "We had an older brother named Bill," teenaged Hart once whispered to five-year-old Amanda. He had to leave the family to make room for you . . ." Set in Montreal, Los Angeles and Vancouver, Matters of Hart is a picaresque tale about sibling rivalry, the joys and pains of family ties.
