What is the author's style in Caleb's Crossing: A Novel by Geraldine Brooks?

The story is told from the first person, past tense point of view of narrator and protagonist Bethia Mayfield. What's particularly interesting about the way Bethia tells her story is that in each of the book's three parts she starts that part's story clearly stating its outcome, or at least a degree of it, then goes back and explains how she arrived at that outcome. In other words, she starts at the ending and goes back to the beginning, dropping enough hints in the first few paragraphs about that ending, or the situation in which she has found herself, to make the reader irresistibly interested in reading on.
