Moonshine and Magnolias (Just Add Peaches Book 1) by Abigail Sharpe

History professor Rob Upshaw just can't resist a good treasure hunt, especially when it involves stealing back a long-lost heirloom. His path leads him straight to The Inn at Fountenoy Hall, but there's a catch - in order to keep the innkeepers from getting suspicious, he must pretend to research the land and its history. Wendy Marsh has her sights set on a successful career in the international hotel industry. She never wanted to be tied to Fountenoy Hall, but she can’t turn away when she inherits it. She's convinced she can whip someone else into shape to take over running the inn without destroying the family legacy. The ridiculously attractive professor is nothing more than a delightful distraction from Wendy's carefully planned life. She's determined to break things off once she returns to her normal, structured routine. Previous experience has taught her that investing in her job was more important than investing in her heart. Caught between the allure of the treasure and the enchantment of Wendy's smile, Rob finds himself falling head over heels for the innkeeper. But with his secrets piling up like missing artifacts, confessing the truth becomes increasingly complicated. And if he doesn’t come clean before Wendy finds out, being stuck in the past is going to ruin his future.
