What is the author's style in Pigs in Heaven by Barbara Kingsolver?

Kingsolver employs the third-person point of view throughout the novel. As a result, she is able to give a balanced portrait of each faction of the argument for custody of Turtle. Sybil Steinberg in her review of the novel in Publishers Weekly writes that one of its strengths is Kingsolver's ability to "make the reader understand and sympathize with both claimants on Turtle's life, the Cherokee Nation and Taylor."
