What is the author's style in Diamonds in the Shadow by Caroline B. Cooney?

Diamonds in the Shadow is told in third-person limited omniscience narration from the revolving point-of-view of the four children: Jared, Mopsy, Mattu, and Alake. In all the character's chapters, the narration is completely reliable. Cooney divides the novel equally between dialogue and exposition, with much of the exposition occurring within the thoughts of the characters, not from an external narrator. The descriptive passages work hard to conjure images of the African civil war, and it is clear that Cooney has researched her novel well and is comfortable incorporating historical information into a successful fiction book.
