Calypso loves the new-old house where she lives with her 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, and even in the local cemetery. She celebrates her adoption on Family Day, and makes beautiful things in Mama Vic's pottery studio. 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. Fun for middle-grade readers. | Haunted Holiday by Margaret M Rodeheaver, Paperback | Indigo Chapters
