Girl unknown : a novel
(Book)

A professor's marriage and family begin to unravel when one of his students tells him that he might be her father. David Connolly is up for an important promotion at the university; his wife Caroline has recently returned to work after years away while the children were little. The recent stresses of home renovation and of a brief romantic betrayal (Caroline's) are behind them. When a student appears in David's university office and says, "I think you might be my father" the fact of a youthful passion that David had tried to forget comes rushing back. Is the girl an opportunity or a threat to their hard-won family happiness?
