Welcome Home, Roxy Carmichael (1990)

Although Roxy left town more than fifteen years ago, her memory has never faded. Her expected return starts to impact a number of lives, including that of her former partner Denton Webb. But it is Dinky, the adopted daughter of the Bossettis and ignored by most of her classmates as a strange loner, who may be most changed. She is convinced she is Roxie's secret child.
