The Duke's Divorce (The Reluctant Grooms Series Volume IV‪)‬

A simple trip to the Scottish Highlands turns into a nightmare for Robert Carlton, the Duke of Cantin. A misunderstood act of kindness results in his wedding, at gunpoint, to Fiona, the Laird Stewart’s daughter. Both Robert and Fiona are distraught by the forced marriage, until Robert comes up with a plan – they will remain married for six months, after which, the marriage will be annulled and Fiona will receive a generous settlement.
Robert’s restrictive contract for his new duchess causes Fiona to rebel. Her impeccable beauty, fiery disposition, and her penchant for finding scandal wherever she goes, take Society by storm, and living with the oppressive duke has her wanting out of their marriage sooner than the proposed six months.
To his astonishment, Robert becomes enamored with the many charms of his unorthodox bride. However, remaining chaste was part of their agreement, though desire and jealousy prove a powerful aphrodisiac.
Convincing Fiona of his love is the hardest thing Robert has ever had to do. But when he thinks he’s won her heart, a devastating secret from his past surfaces. Will the promise of an uncertain future with Robert be enough to keep Fiona from filing divorce papers of her own?
