This is a grand journey of chasing light and the author's journey of self-discovery. At the end of the book, the author has a deeper understanding and thinking about life and aurora. I realized that everything in the world has its meaning. I am also very touched by the efforts made by some people all their lives, just to pursue an idea or goal. I am even more amazed at human's ability to endure pain, endurance and adaptability after promotion, but in any case, although the future is full of variables, hope is always ahead.
