Holly's back, and so are those cats! This time Mom and William have made her move to a new house, and the neighbors are really weird. What is that silver machine in the backyard next door anyway? Is the boy who built it really a mad scientist? And what has he done with George Cat?
“Those readers for whom Holly is already a friend will appreciate this further domestic adventure; those who don't yet know Holly need to be introduced as soon as possible.”
