Very strange chips

This is a story about a sleepy town called Pena, a place where the air is filled with stories of children disappearing without a trace. Poppy is about to spend the summer with her grandmother in Pena. Boring... However, strange things start happening very soon! The girl finds a notebook with a cover as if made of the finest silk, her grandmother says that sugar cubes must be locked up at night to prevent any harm, and meanwhile children are disappearing in Pena. This started many years ago. And since then, there are fewer and fewer children in Pena. Teaming up with a new friend named Erasmus, Poppy sets out to find out what is happening in the town. How is the abandoned weaving factory located in the dark Mysterious Forest connected to the disappearances? Why do people shudder at the mention of the factory's last owners - the strange Sheppards? For middle school age.
