What is the author's style in Whirligig by Paul Fleischman?

Every odd numbered chapter, from the first to the ninth, is in the third person. These chapters told from Brent's point of view by a narrator with a limited omniscient view, a narrator who knows Brent's thoughts but is not Brent. There is no information in those chapters that is not known to Brent, and no other thoughts except his. These chapters tell a story about Brent that progresses in time and place in a linear fashion. The other chapters vary in point of view.
