The Untamed Duke

They call him the Winter Wolf.
Nicholas March, the Duke of Richeforte, has few morals, fewer friends, and a notorious lack of honor. And his heart? What remains of it is cold, desolate and locked away. He learned long ago the lessons of betrayal. Never trust a woman. Recognize that others, even friends, will expect the worst of him. And no matter the cost, always retain control of any situation. It is infuriating when a slip of a girl cracks his icy façade.
Irrepressible Grace Willsdown is neither daunted nor impressed by the rigid duke. She has no patience for the silly games of London's society and no desire for the imprisonment of marriage. When a secret encumbrance against her home is revealed, everything she treasures is cradled in Nicholas March's palm. She makes a Devil's bargain to save it all.
Five nights of secret pleasure with the duke and all claims will be dissolved. But neither Grace nor Nicholas anticipate the depths of their craving following that first night. It is a desire that won't be denied. Consuming. Blistering. Tender and brutally passionate. The boundaries become distorted.

What is the part of the bargain? And what is true emotion?
The key to unlock their love is within their grasp. Will they brave the storms and fires? Or turn their backs when their five nights are done?
