Book excerpt: South of the Big Four is a gracefully told, arresting look at an America in which the center no longer holds, where a new kind of forgiveness and understanding must be found. In the tradition of A Thousand Acres and A Map of the World, the novel's sudden truths and lasting images transcend the daily lives of its Midwestern characters to create a penetrating, resonant story, made all the more remarkable because it is the author's debut.
