The Runaway Duchess by Loretta Levine

“I agree to keep my hands off you, wife. Unless you put yours on me first…”

Desperate to escape her abusive stepmother and her upcoming nuptials, Caroline flees her own wedding to build a new life in a village where no one knows her name.
Damien will have no duchess but Caroline. He has wanted her for five long years, so when he lifts the veil at the altar to find her stepsister beneath it, he is determined to hunt down his runaway bride and bring her home.
Given his fearsome reputation, Caroline does not trust him. But a child has been left on his doorstep, and Damien needs her. She agrees to become his wife on a single condition: he is never, ever to touch her.

Only… Resisting her husband proves far more difficult than running from him.
