About the book: 2022 / Bayu-Bai is an old broken doll. Sisters Lucy and Antonia found her by the river and took her home. After some time, the girls notice that Bayu-Bai is not an ordinary doll. She takes revenge on Antonia’s offenders and seems to be trying to quarrel between the sisters! It is clear that Bayu-Bai is up to something evil... Lucy goes to the library for answers and finds in an old book the story of Bayu-Bai's previous owner. It turns out that the doll has its own evil mind and is clearly up to no good, and its “help” is becoming more and more dangerous... But how to find a way to deal with the old toy before it’s too late?!
