When the ghost of a murder victim appears in Last Chance Books, middle-aged bookstore owner Willa Chance must find the ghost's killer or risk being haunted with its unwanted advice forever. Too bad the ghost suffers from amnesia and only has a few scant clues as to the identity of the killer. That's okay, though, because Willa has a pretty good idea who did it...until her investigation turns up additional suspects with curious motives.

Meanwhile her cat, Pandora, is on the hunt for a mystical kitten that the cats of Mystic Notch must bring into the fold before the kitten is enticed to the side of evil by a powerful foe.

When Willa's own life is threatened, she enters into a race against time to figure out the identity of the killer before she becomes the next victim.
