This book is a thrilling adventure about a boy and his little sister threatens her brother. On his birthday she ruins it by telling jokes about her brother to his friends. One day his father buys a antique clock and warns his son not to touch it, but without his father noticing he turned the cuckoo bird the opposite it used to be facing.
I thought it was kind of a sad story because you would not want a little sister who threatens your life and plays tricks on you. Also I thought the book was pretty scary when the clerk tells a story about the cuckoo clock. The cuckoo clock was really old and it was also cursed and weird things happened to the people who messed with it.
