What is the author's style in Down These Mean Streets by Piri Thomas?

The book is written in first person from the limited point of view of the author. The point of view and the voice are acceptable and believable and it can be argued these are the only effective means for the author to tell this story. The limited point of view means the reader does not know what is going on except at the moment when Piri himself is interacting with others. For example, once he leaves his family's home, the reader does not know anything about the family until Piri again interacts with them.
