I second Snow Falling on Cedars
And, I have some more recommendations, since I taught this subject to high school English students. We started by reading Farewell to Manzanar - http://www.amazon.com/Farewell-Manza...4030533&sr=8-1
Also read some poems by Janice Mirikitani, from her collection We, The Dangerous: http://www.amazon.com/We-Dangerous-N...4030630&sr=1-3
We discussed this newspaper article: http://community.seattletimes.nwsour...7&slug=2327953
We also read an article by William Booth, in the Washington Post, called "A Lonely Patch of History". I can't find it online right now, but I did find this, that sites the article and looks good: http://www.lostmag.com/issue10/manzanar.php
. It also includes a link to Ansel Adams photos from Manzanar.
And here's one more newspaper article: http://www.paloaltoonline.com/weekly...9.COVER09.html
Finally, PBS did a documentary called Children of the Camp, with website information available here http://www.pbs.org/childofcamp/index.html
Happy exploring on this very sad/very important subject...
