The bubble always reminds me of innocent, innocent childhood, bringing me back so many sweet memories of the back-to-school. Perhaps that is why when I first saw the book "Bubble to the sky" by Nguyen Nhat Anh, I was impressed with this book. The story revolves around the character Thuong - an 11th grader. Because of circumstances, Thuong had to help his mother by selling candy pulling out of school, and getting used to life on the street. There, he made friends with the poor and learned many things not in books and schools. The semi-bubble girl named Tai Khon is innocent and many dreams are also concerned to help Thuong escape her inferiority complex and be confident. I still caught sight of my childhood image, with kites flying in the sky. So mellow! Reading "bubble to the sky" gives me such feelings, the pure emotions of adolescence, the familiar emotions of each person rushed to bring with it a little sadness, mourning, a little lust of childhood days. "Bubbles to the sky" will live forever in my mind like a fairy tale in real life.
