What is the author's style in Dope Sick by Walter Dean Myers?

The point of view of this novel is first person. The narrator is Lil J, a drug addicted teenager who is on the run from the police. Most of the novel takes places in an abandoned building where Lil J talks to an apparent homeless man who appears to have a magical television that he uses to help Lil J see the mistakes he has made in his past and find a way to make things better in the future. At the end of the novel the reader realizes most of the events are taking place inside Lil J's mind as he sits on a rooftop, desperately trying to find a way out of his situation that does not include suicide.
