She has a great blog*, and this post was brilliantly hilarious. I think she totally pulls off the second person future narration!
(If you want to see second person narration done brilliantly, read Italo Calvino's amazing book, If on a winter's night a traveller. Go to the link and click on the Look Inside; it has most of the first chapter so you can get a feel for it. Calvino alternates between chapters in second person, in which you, the Reader, are the protagonist, and chapters which are the book you are trying to read. Except that there's a problem with the book, and you end up reading the first chapter of a number of different books, each with its own style. And as you try to solve the mystery of the defective book and get a story that you can actually finish, you meet the Other Reader, who joins you on your quest. It's a lot of fun, and it's an homage to books and the reading experience, so if you consider yourself a Reader, you should read it.)
(As a writing exercise I tried my hand at Calvino's technique and wrote a sci-fi novella that alternates between second and third person and parodies a number of different sci-fi/fantasy tropes. It's really bad but I had a lot of fun doing it!)
(I think I could do an entire novel in parentheses: I bet that hasn't been done before!)
*This is the first time I've thought of a use for twitter: obviously sending you to read someone else's blog isn't a blog entry, but I felt like telling people about Kiersten White's post, so I guess I could have tweeted it. If I had a twitter account.(Actually I think I do have a twitter account, but I only ever used it once to enter a contest to win a Robin McKinley book. (I didn't win.) I'm not sure I even know how to get to it, or what user name or password I might use to access it.)(I feel about Twitter the way I feel about the butterfly stroke in swimming: I'm quite happy not knowing how to do it.)
