The Duke’s Improper Bride by Rebecca Paula

As an agent of the British crown, Issac Barnes not only expects trouble, but he’s exceedingly good at escaping it… until Corisca. After the mission goes wrong, he’s sent to recover in the Scottish Highlands where he swears off complications, including women. That all changes when a beautiful woman marches toward him in a field one morning, determined to conquer the world, and in turn, his heart. Sparks fly when this secret duke falls for the spirited Highlander, but their love affair will be anything but easy if they’re going to have a future in London.
After a horse riding accident leaves Nora MacAllen with a severe stutter, she’s shunned from London society. Now she spends her days hiking mountains and preparing for an arranged marriage to help her father’s budding political career. But when she meets a mysterious and handsome English man one morning, her world turns upside down and she’s left questioning if love is worth the risk of finding her voice once again or if it’s safer to guard her heart and remain an outcast.

THE DUKE’S IMPROPER BRIDE is meant to be read between books 1 and 3 of the Ravensdale Family series. If you love charming cinnamon roll heroes, strong heroines, and sweeping romances in the Scottish Highlands, you’ll love this book.
