What is the author's style in In the Lake of the Woods by Tim O'Brien?

The story is centered around a convoluted plot and the mystery of the story is never resolved. While the words used in the story will be familiar to most readers, the presentation is sometimes confusing and readers may have trouble understanding all aspects of the story. The story is not presented in a chronological order and the author sometimes skips around between time frames within a single chapter. This may be confusing to some readers as well though the author does an adequate job of keeping scenes and situations separate.
