A Duke Always Breaks The Rules

After being forced into a marriage arranged by his father, Lord Charles Newberg, Marquis of Rockhurst returns to London to resume life as usual without a care for the young bride he left behind. Even after he acquired the title Duke of Avanley, upon the premature death of his father, he saw no reason to change the parameters that he had set for his marriage.
As the daughter of the Earl of Montrose, Isobel always knew her marriage would be arranged by her father, but she had not expected her new husband to be so callus nor had she expected her life to be turned upside down by one vivacious duchess who refused to take no for an answer. Now she finds herself in London, ready to take her place as the new Duchess of Avanley, regardless of her husband's feelings on the matter.
His young wife showing up in London was unacceptable, but her stubborn refusal to leave kindled a spark inside him. Could he put aside the resentment he felt at his father's interference in his life to give them a chance at love or was their marriage doomed from the beginning?
