What is the author's style in The Giver by Lois Lowry?

The Giver is written in the third person ("he/she"), but the narrative point of view is that of the main character, Jonas. From the first to final paragraph of the novel, the reader is always inside the head of Jonas, feeling with him the anxious moments leading up to the announcement of his Assignment, and feeling with him both the pleasurable and the painful memories passed on by The Giver.
