Love by Deception — Debra Elizabeth

Content with her life as a lady's maid, Isabel Knott learns the father she never knew has left her a fortune. The news comes with one restriction--she can never reveal his name. Isabel falls in love with Colby Tisbury, but with her nonexistent pedigree his father, Lord Tisbury, will never accept her as his daughter-in-law.

Colby Tisbury must marry, and soon. If he doesn't find a bride before the end of the Season, his father will supply one. Then Colby meets sassy Isabel Knott, and everything changes--but can he go against his father's wishes and marry a girl utterly lacking in family and connections? Isabel is forced to make an impossible choice - reveal her secret identity and bring shame to her true father or lose Colby forever.
