"Olivia's mom, Ellie, is always cooking up new schemes, but her latest idea has Livie and Maddie especially excited. Ellie's converting an old boarding house into an arts and crafts school--one that, of course, houses a kitchen for those interested in baking. But right as renovations start, the workers discover a pile of bones buried within the boarding house's walls, evidence of a long forgotten crime. A silver necklace with a cookie cutter charm is found within the remains, convincing one of the workers that the bones are the remains of her father, who's been missing for over five years. Of course, Livie and Maddie can't resist the allure of investigating. But they're about to discover that digging up the secrets of the past can be deadly dangerous" --
