Forever Her Duke by Scarlett Scott

From bestselling author Scarlett Scott comes a scorching-hot series that returns to the Notorious Ladies of London world. Six friends, one house party, and a whole lot of scandal…

Vivi, the Duchess of Bradford, loved her husband from the day they first met. She was an unabashed hoyden. He was the heir to a dukedom and her older brother’s best friend. She vowed to marry him, but she never could have imagined just how dreadfully that youthful promise would go awry, shattering her hope for a future.
Having spent the past year in England while the duke has been abroad, she has thrown herself into a cause that won’t lead to more sorrow. She’s content with her growing circle of friends in the Lady’s Suffrage Society and is doing her utmost to banish the Duke of Bradford from her heart and mind for good.
Until she discovers she has an unexpected guest at her country house party, and it’s the husband who left her. Not only is he back, but Court is far more sinfully handsome than she remembered, and he wants the one thing she isn’t prepared to give—her complete and utter surrender.
