This book is very good! The experience of the protagonist John Christopher made me empathize with him. His perseverance in the face of difficulties and his persistent pursuit of music are admirable. His character matures over the course of the story, much like we do when we face setbacks in life. Moreover, the description of music in the book is very vivid, making me feel like I can hear the passionate melody. In short, this is not only an epic about music, but also a good book that can touch people's hearts.
