What is the author's style in Snow Falling on Cedars by David Guterson?

Snow Falling on Cedars provides an excellent example of an omniscient narrator. The narrator moves easily in and out of each character's thoughts, memories, and feelings, and then back to objective reporting of events. Guterson applies his imagination to a great deal of research to write with authority about the experience and expertise of each character. As a result, the narrator talks about fishing, farming, adolescent love, Ishmael's father's publishing ventures, wartime horrors, Japanese culture, the history of Amity Harbor, and autopsies.
