The Duke's Ruthless Vow: A Regency Romance Story

By Margot St. James

"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
