“Sometimes we don’t even realize that the destinies and lives of others depend on our actions or words.” Jay Asher's 13 Reasons Why Loneliness in children and teens is common for a variety of reasons, including poor communication skills and peer problems. Children are susceptible to bullying, which often occurs due to a lack of understanding of their differences. Schools are not always ready to solve such problems, preferring to ignore them. The main theme of the book is school bullying and the relationship between parents and children. The life of the main character is not easy: her parents are divorced, her mother does not pay attention and takes her daughter to a completely unfamiliar city. At school, Sasha is constantly bullied, but she has no defenders. One day, after preventing a classmate from copying a test, he becomes an object of bullying. But soon Dima appears and her life changes... The book is full of ambiguous and frightening moments, but full of moments of friendship, trust and honesty.
