When I read the book Farwell to Manzanar I thought it was a sad book because the government forced Japanese people to live in internment camps for two years. I think the government did this because they were scared that if Japanese people had contact with Japan then they could give signal to war. I give this book 4 stars because it was a good book but kind of dull.
