Calypso loves the new old house where she lives with the two mamas. She doesn’t even mind that a ghost lives there too – until the ghost ruins the mamas’ holiday cookie party. Is there something he doesn’t like about parties? Or holidays? Or cookies? Calypso is determined to find answers, and clues turn up in the most unexpected places – the library, her friend’s house, even in the local cemetery. But time is running out. With her cat Whiskers, and with help from her new friend Abbey, Calypso races to solve the mystery – before the ghost can ruin their next party. A fun holiday story for middle-grade readers.
