What is the author's style in The Lost Boy by Dave Pelzer?

The story is written in first person by David Pelzer. The point of view is actually the only way the story would work since it was David's story and therefore only David could have told his thoughts, fears, and experiences. The story takes place in and around Daly City, California, where David lives as a child. David's life with his mother happens at "the House", then David lives in a series of foster homes in the area. David describes a series of homes, neighborhoods, and schools where David finds himself over that time.
