What is the author's tone in Farewell to Manzanar by Jeanne Wakatsuki Houston?

The tone of this book is straight-forward. Jeanne describes events as they happened, according to her memory. The events are told as a story, the story of a young girl held in an internment camp. She describes events and situations as they were, as she remembers them, recalling facts and events that give this history the feel of a story. She remembers little things like the extreme torture which lack of personal privacy in the open stalls of the latrine brings to her mother, until she learns to carry around an Oxidol box to use for a privacy screen.

She describes the fear felt by her family both after their Papa is taken prisoner and after he is returned. They fear not knowing what is happening to him, and fear not knowing what he will do next.
