To Kiss a Thief (Runaway Desires #1)
Susanna Craig

Sarah Sutliffe, Lady Fairfax, dreams of love—until she overhears her new husband proclaim his heart will never be hers. Devastated, she offers no defense when a sapphire necklace disappears during a ball and she is accused of its theft. Instead, she runs away from the scandal…and the heartbreak.
St. John, Viscount Fairfax, has sworn never to love again. How could a mousy merchant’s daughter tempt him to break that vow? Three years after Sarah vanished, St. John uncovers her hiding place. Now, he’s out to prove she’s a thief before she steals his heart.
