What is the author's style in The Chocolate War by Robert Cormier?

The Chocolate War is written from the third-person omniscient point of view. Generally, each chapter is in one person’s perspective but there are a few exceptions. There are a few montage-type chapters that show collectively what different boys are thinking about the chocolate sale. Cormier does this to show the school’s feelings outside of Jerry and The Vigils.

Most of the chapters are from the perspective of Jerry, The Goober, or Archie. The effect of Cormier switching viewpoints allows for the readers to sympathize with different characters, even Archie. But, Cormier never allows Brother Leon’s viewpoint suggesting that he is not a character with whom one can be capable of sympathizing.
