This book is by David Guterson. I have only started reading it myself, I found it in the library in second hour. Here is what the back says;

San Piedro Island, north of Puget Sound, is a place so isolated that no one who lives there can afford to make enemies. But in 1954 a local fisherman is found suspiciously drowned, and a Japanese American named Kabuo Miyamoto is charged with his murder.

In the course of the ensuing trial, it becomes clear that what is at stake is more than one man's guilt. For on San Piedro, memory grows as thickly as cedar trees and the fields of ripe strawberries-memories of a charmed love affair between and white boy and the Japanese girl who grew up to become Kabuo's wife; memories of land desired, paid for, and lost. Above all, San Piedro is haunted by the memory of what happened to its Japanese residents during World War II, when an entire community was sent into exile while its neighbors watched. Gripping, tragic, and densely atmospheric, Snow Falling on Cedars is a masterpiece of suspense-but one that leaves us shaken and changed.
