The Duke She Married by Jessie Clever

Orphaned and destitute, Lady Amelia Atwood must marry to save her family from utter financial devastation. Lost between her sisters, neglected by her father, and scorned by her mother, Amelia learned being close to people only brought hurt and loneliness, and she avoids them at all costs. But if she wishes to save her sisters, she must sacrifice herself.

To the Ghoul of Greyfair.

Disfigured by the fire that killed his wife, Lucas Bennett, the Duke of Greyfair, hides in his remote island castle, avoiding the rumors that suggest he murdered his wife. But when his need for an heir drives him from his lair, he strikes a bargain with the desperate Earl of Biggleswade for the hand of his daughter. Lucas’s plan is simple, but he’ll soon discover she’s not the timid debutante he had bargained for.
