What is the author's style in The Last Olympian by Rick Riordan?

The point of view of this novel is the first-person perspective. Percy Jackson is the narrator, telling the story from his memories and feelings. Percy knows of only the events that occur around him, his own feelings, and what is revealed to him through prophetic dreams.

The author tells the story mostly through dialogue with other characters, but also relies heavily on Percy's personal thoughts and feelings. The use of dialogue with other characters, and the view into Percy's feelings and private thoughts helps to tell the story of Percy's growth from a boy into a man and leader of his people.
