Who is the narrator, can she or he read minds, and, more importantly, can we trust her or him?
Third Person (Limited Omniscient)
Though we spend pretty much the entire book with Abyssinia (except for that pesky first chapter, in which she hasn't been born yet), and the plot is definitely focused on Abby's coming of age process, she doesn't narrate the story. Instead someone else does—someone who isn't involved in the action in any way, shape, or form. This person is our trusty third-person narrator.
Just because they aren't in on the action doesn't mean they aren't in on Abyssinia (and occasionally other characters, too), however. For instance, when Lily Norene has a stroke, our narrator is right there with her, feeling the pain in her skull, seeing the fruit on the floor, and struggling to get up the stairs (28.14-15). And we often know what Abby is thinking, slipping into her dreams, knowing when she wonders about her father's whereabouts (18.6), and more. That's the limited omniscience bit to our narrator—they can hop into some heads sometimes, but not all the heads all the time.
