What is the author's style in Among the Hidden by Margaret Haddix?

The language in Among the Hidden is targeted toward older children. The protagonist, Luke Garner, is 12 years old when the novel begins and since the story is written from his point of view, the language reflects language that a 12-year-old might use. Author Margaret Peterson Haddix does a tremendous job of conveying complex concepts in very simple language. To accomplish this goal, she relies heavily on words that convey emotion.
