What is the author's style in A Boy Called H by Kappa Senoh?

Although A Boy Called H is an autobiographical novel, the story is told in the third rather than the first person. In this case, the point of view—the consciousness through which the story is told—is limited to H. Other characters, and all situations and events, are seen through his eyes. And since H is a young boy, the style employed to convey his point of view is for the most part quite simple. The sentence structure is simple, and the vocabulary is appropriate for a boy of H's age. Also, the story is told in a straightforward, chronological manner. There are no flashbacks (except in chapter 2, when H tells of his parents' backgrounds) or other more sophisticated literary devices.
