What is the author's style in Song of the Wanderer by Bruce Coville?

This book is written in a narrative mode, which means the action is explained by a semi-omniscient narrator. The narrator is never named, but they always knows what is going on around Cara. The narrator occasionally tells the reader what Cara is thinking as well, but the narrator never ventures into any of the other characters head. Outside of Cara's inner-monologue, everything else written in this book is either dialogue between characters, or an explanation of what is currently happening. Occasionally an event from the past is mentioned, it usually involved Cara's grandmother Ivy, and is most likely told by Jacques, the Queen, or Grimwald.
