In this book, the main character, Brian, who is in pain because his parents divorced, was traveling on a light plane to meet his father in northern Canada for the summer vacation. It is the story of surviving alone on a deserted island. The process of a boy who is only 13 years old at the most, making a fire, making a nest, and even making a mini-raft, looking for food and surviving with a single hatchet given to him by his mother, is very pathetic. Then, finally, he found the survival pack mounted on the plane, and the moment he tried to have a supper with emergency food there, he met a futile reversal ending.... It was a happy but ridiculous ending. Because I was really looking forward to a more interesting ending. I really enjoyed this book, and I want to read it again in the future.
