What is the author's style in The Long Walk by Stephen King?

The book is written in third person and is limited to Ray Garraty's perspective. While it would sometimes be beneficial to the reader to see things from other walkers' points of view, the limited perspective actually works quite well in the building of suspense. For example, the reader knows that Barkovitch is having trouble, but there's no indication the level of his madness until he tears his throat out. That abrupt behavior, with no warning, is an excellent way to make the reader literally jump with understanding.
