Sisters Harper and Flannery weren't exactly best friends, especially after their mother's illness and funeral. But neither expected the inheritance they received: a lighthouse in Moonglow Cove. And their grandmother's will has a stipulation: the two of them must live there, and compete in a baking challenge involving a hundred-year-old sourdough starter. If either one give up, or fails to keep the starter alive, they lose the lighthouse. Will Harper and Flannery be able to come together and work out their issues? -- adapted from back cover
