Author Percival Everett has challenged the schism of race in such satirical novels as “Erasure” (basis of the Oscar-winning film “American Fiction”). His latest, “James,” re-tells the story of “Huckleberry Finn” from the point of view of Huck’s enslaved friend, Jim, for whom language becomes a shield, and an avenue toward freedom. Everett talks with correspondent Martha Teichner about his writing, his artwork, and his penchant for privacy. Source
