Ralph by Edith Byrd

A Duke torn between duty and love. A servant mother with a dangerous secret. A daring plan to protect them all.

Ralph, the new Duke of Lancaster, is torn between his sense of duty and his heart. After losing his father and then his elder brother on the battlefield, he’s faced with the difficult task of taking over the dukedom.
However, when he discovers that his late brother has fathered a child with a servant girl, Teresa, Ralph must decide between protecting the child or risking a scandal by casting Teresa aside.

To buy time and weigh his options, Ralph takes Teresa to an old family manor and hires Miriam, a young woman with a secret of her own, as their housekeeper.
