Enter the world of the most notorious gambling den in London, where matches are made... unusually. Welcome to the world of THE LYON'S DEN: The Black Widow of Whitehall Connected World, where the underground of Regency London thrives... and loves.

He loved her at first sight…but she was his enemy’s daughter.

Dáire O’Neill has a terrible problem: he’s fallen in love with his enemy’s daughter. He met her by accident, but loved her from the moment he first saw her. She savors their friendship, but he won’t go beyond it.

Despite her father’s scurrilous reputation, Blanche has built a good name for herself—and a respectable business. When the man she met by accident appears uninterested in marriage, she goes to Mrs. Dove-Lyon to secure a husband for herself—and a new life.

When Dáire O’Neill hears that the man Blanche will wed is not the one Dove-Lyon chose, but one her father has put in his place, what can he do if not save her from her own father—and the life she will hate?

He’ll never possess her…but he’ll set her free from all she despises. Even him.
