Some writers have the gift of channeling living breathing people in their fictional characters. Charles Dickens and J. D. Salinger did. So does Sherman Alexie.
Arnold Spirit is the star of Alexie's The Absolutely True Diary of a Part-Time Indian. Arnold is a charismatic underdog. Born with water on the brain, he lisps; he stutters.
