I recommend to young readers who has a fear of death.
Novel was written by the author when he was in his 50s, so it can be easily misunderstood by a young reader. However, I found the book pretty insightful breathing my 21st year in this world. The unique perspective on death (which is a sensitive topic for me). Thoughts about immortality. Understanding of multiple personalities living in each of us and trying to fit in one body.
