What is the author's style in The Time Paradox by Eoin Colfer?

The novel is written in the third-person omniscient point of view. The author tells his story from the point of view of many characters, but most of the novel is seen through the eyes of the main character. The author often moves into the minds of other characters when something happens that Artemis either cannot be aware of or when the opinion of the other character is important to the overall plot of the novel.
