Dorian Whitaker, Duke of Holland, needs an heir after his so-called "fairytale marriage" ended in disaster. When the intriguing bookseller he's hired to liquidate his late wife's library finds love letters revealing an affair, he is drawn into a mystery alongside a lady whose sharp intellect dazzles him and dares him to imagine a new adventure outside the gilded cage of the Ton. If anyone found out Caroline Danvers writes erotic novels under a pen name, she'd face utter ruin. Except her latest hero inspiration is none other than the Duke of Holland--a man with the power to destroy her family's bookshop. And yet the real man proves to be so much more than the character she created. Even as they expose the dark secrets of his past, she knows he can never discover her own. But the more time they spend together, the more tempting it is to rewrite their ending and turn fantasy into reality.
