What is the author's style in The Aguero Sisters by Cristina Garcia?

One of the most complicated and intriguing aspects of Garcia's novel is its shifting perspectives. Although Reina and Constancia are at the heart of the novel, these two protagonists (the central characters who serve as a focus for the themes and incidents of the novel) don't tell their stories in their own voices. By interspersing different points of view, Garcia gives the reader information that her characters don't possess. For instance, the reader knows from the opening pages that Ignacio murdered his wife, but neither Constancia nor Reina knows this until the very end of the novel.
