"You think a signature can destroy me, Mrs. Davenport?" the Duke leaned in, his voice a low growl. "I will make you wear my ring until you forget your own name." Eight years after her father’s ruin, Clara Davenport returns to Mayfair with a fortune and a vendetta. Her target: Sebastian Kincaid, the Duke carrying the legacy of the man who stole her life. He is the Ruthless Duke , a pillar of granite who rules the ton with an iron cane. She is the Vengeful Widow , an ice queen in black silk armed with deadly secrets. When Sebastian uncovers her sabotage, he traps her in a public, binding engagement to silence her. But as their barbs turn into breathless whispers, the cold friction of their war ignites a fire neither can extinguish. "I sought to ruin you, Ashcroft," she breathed. "Then why," he rasped, "are you the only thing I want to save?" Amidst the storm-battered cliffs of Cornwall, secrets emerge that shatter Clara’s reality. She must decide: finish her work of ruin, or surrender to a passion that threatens to burn their empires to the ground. Perfect for fans of Bridgerton and Evie Dunmore, this steamy Regency romance features a battle of wits and a high-stakes fake engagement. One-click your copy of The Duke’s Ruthless Vow today!
