Captivating the Duke

Zachary Sheridan, the eligible and charismatic Duke of Winchester, is faced with a dilemma. In a youthful misadventure his father's life was saved by his friend Euston. As a token of his gratitude Winchester signed a document promising his firstborn son in marriage to Euston's daughter. Both men are now dead, but Euston's widow is intent on having Zach honour the agreement to marry her daughter Fiona.
Whether or not the document she possesses is genuine, Zach cannot chance bringing dishonour on his family by challenging the claim and risking a breach of promise case.
Meanwhile, Frankie St John, Zach's alluring widowed neighbour, is being blackmailed by her brother-in-law. He possesses a document which, if made public, would reveal a devastating secret that would see her ostracized from society. Worse, she would lose the respect of Zach, the man she secretly adores.
Can Zach and Frankie find a way through this web of intrigue, save the Sheridan family name and find the happiness together they so richly deserve
