What is the author's style in Julie of the Wolves by Jean George?

Language is a key element of Julie and the Wolves. From the first pages, Miyax's survival depends on her ability to observe, interpret and mimic wolf language, both body language and spoken language. In some cases she can recognize parallels to human language. The play gestures of the puppies are similar to human play, and Silver's reprimand, taking Miyax's shoulder in her jaw when she attempts to nurse, needs no interpreter. It takes a deliberate effort, though, to identify and learn the grunt-whine which summons, the grovel which apologizes and the glare which turns away.
