She needs to escape …
When Miss Annabel Ridley learns of her fiancé’s shocking betrayal, she knows she cannot proceed with the match—even if it means defying her father’s wishes and igniting scandal. Trapped between duty and danger, she flees to the one man powerful enough to help her—the Duke of Halmesbury, a stranger with a formidable reputation … and a surprising offer.
He needs to make amends …
Philip Markham, Duke of Halmesbury, has spent years hiding from heartache and mistakes he cannot undo. When a determined young woman arrives on his doorstep, desperate and brave, he sees an opportunity to do one thing right. He proposes a marriage of convenience to protect her—but as they draw closer, he finds himself yearning for more.
Can two hearts bound by necessity learn to love—and find peace in the providence neither dared to hope for?
As old wounds resurface and secrets come to light, Annabel and Philip must learn to trust one another—and to believe that sometimes, the most unexpected unions are those most touched by grace.

If I remember correctly, I got The Duke's Sacred Vow as a freebie. Sometimes, I don't expect a lot out of freebies, but I've been in the mood for historical fiction to get me out of my fantasy rut. So I decided to take a chance on The Duke's Sacred Vow, and I was pleasantly surprised.
Annabel is engaged to a man that she's known for a long time. They've been friends. Richard was a close friend of her brother's, but as she got older, Richard became a confidant for Annabel. She thinks they have a love match, but one day, Annabel stumbles upon Richard and her maid in the stables. After that, Annabel is determined to get out of the marriage. Yet Richard plans to move forward with the wedding, and Annabel's father won't hear of ending the engagement either. Annabel seeks out Richard's cousin who lives fairly close by in hopes that he will talk sense into Richard. He is heralded as an honorable man, and he is a duke. Well Annabel is surprised to find that Phillip's solution to her problem is to marry her himself.
Phillip is a widower. He needs to remarry to ensure his duty to produce and heir. Yet he dreads the idea of the marriage mart. And his previous marriage was a struggle between two ill-suited people. He doesn't want that. Annabel surprises him by showing up at his house. However, he is immediately impressed by her. He makes an impulsive offer, but it will solve two problems at once. He can rescue her from his roguish cousin, and he can secure himself a wife. They both know they wouldn't be marrying for love, but Annabel is satisfied with an honest marriage with mutual admiration.
The two do get married within a week of meeting each other. They both have pasts that need to be worked through. Phillip never really grieved his previous wife nor the falling apart of his relationship with his cousin which he has just made more complicated by stealing his cousin's bride. Annabel falls first and she isn't sure whether Phillip married her because he was trying to get revenge against his cousin. Plus she and her brother are estranged, and she has no idea why.
I was hooked into this story early. And I never had any complaints with the writing style or pacing. I will say that I was so impressed with the prayer life and personal relationships of Annabel and Phillip. I feel this is probably more of a reflection upon Isabel Jacobs (the author) than the characters themselves. The frequency that these characters spoke to God was so impressive. This is a situation where many might find it idealistic, but I find it inspiring. And I wish more literature showed the world as it could be rather than as it is. I will be reading more of her books just to see if this is as common with her other characters as it was with these two. But it helps to remind me to be as constantly in conversation with God throughout my day.
Favorite quotes:
-“You must pray over this, child. If the Lord opens a door, it’s ours to walk through, but you must be certain it’s not one you’ve forced open yourself.”
-God is so kind, she thought, pausing at the door. He does not always answer in the way we expect, but He never forgets us.
-“But I would rather stand before God having erred on the side of mercy than having hardened my heart.”
-“You see, the world turns something holy into something coarse. But Scripture speaks of marriage as a picture of Christ and the Church. Tender, patient, honoring. A true husband waits for his bride, honors her hesitations, and sees intimacy as a gift, not a demand.”
The Duke's Sacred Vow gets 4.5 Stars. It's one of my favorite tropes--marriages of convenience. I loved the personal relationship the two main characters had with God. My one critique is that Phillip nearly had to fight himself to figure out that he loved Annabel, yet he pulls the "I've loved you since the first day" thing. If not for that, I might have given this one 5 Stars. Have you read The Duke's Sacred Vow? What did you think? Let me know!
