When Kelsie Walsh inherits her grandmother's farm, she's ready to move her cupcake business back home to Tennessee. She wants to get into the business of hosting ranch-style weddings, and the property's caretaker certainly turns her mind to romance. But before Kelsie can get that off the ground, she discovers her grandmother may have met a not-so-natural end.

While searching for clues as to what really happened to Gran, she comes across a litter of rumbly tumbly kittens. The five of them unwittingly reveal to Kelsie that her grandmother was actually a witch and that she, too, has magical powers.

Armed with a wand, a mixing bowl, and five furry friends, Kelsie sets out to find her grandmother's killer before he strikes again.
