A Life's Morning by George Gissing

A cultivated poor young woman Emily Hood from a small town in the north of England works as a governess in a wealthy country family. She falls in love with her employer's son, Wilfrid Athel, and the two are engaged. However, during a visit to her parents' home, she is confronted by her father's employer, Dagworthy, who threatens to expose her father as a thief unless Emily marries him.
