My Fair Footman

Avery was born a girl. But when the countess's own son dies, a contract is made between Avery's mother and the earl: to raise Avery as the boy they lost. She binds her chest and dresses as a man for work as the Earl of Baenbowie's footman—an occupation reserved only for men. No one outside knows all this, but she has one wish: make it to 18 undiscovered so she can finally live her life as a woman. As her feelings for the Earl grow stronger, can she guard her secret until then?
