What is the author's style in A Virtuous Woman by Kaye Gibbons?

The novel is told in the first person point of view through the eyes of two separate narrators. Jack begins the novel four months after Ruby's death. Jack recalls Ruby's illness and her funeral, as well as specific moments of their lives together. In alternating chapters, Ruby narrates the novel several months before her death. Ruby also recalls important moments in her life, including her first marriage and significant times during her marriage to Jack. Each chapter plays off the one before, continuing the narration as though Jack and Ruby are in the same room together attempting to tell the same story to a visitor.
