Ninety years ago, Millie Sullivan's great-grandmother was a guest at oil tycoon Howard Dawkins' palatial estate on the shore of St. Simons Island, Georgia. Now, Millie plays a 1920s-era guest during tours of the same manor. But when her grandmother suggests that there is a lost diary containing the location of a hidden treasure on the estate, along with the true identity of Millie's great-grandfather, Millie sets out to find the truth of her heritage--and the fortune that might be hers. When security guard Ben Thornton discovers her snooping in the estate's private library, he threatens to have her fired. But her story seems almost too ludicrous to be fiction, and her offer to split the treasure is too tempting to pass up . Get ready for a romantic escapade through dark halls and dusty corners that will have you holding your breath and sighing with delight as two charming characters get caught up in the adventure of uncovering the past and finding their way to an unexpected future.
