First person

Shad is a character in the book and yet he has the ability to narrate the events and experiences he participated in, as well as being able to present his own thoughts and feelings about everything he is going through. When a character is also a narrator we can call his narrative voice "First person." This type of narrative voice can be identified when the narrator is also a character in the story and tells how everything happened from his own point of view. Also, this type of narrative voice has many personal pronouns like I, my, me, we.
