Whatever, I was introduced to Jo Walton's alternate earth history/mystery Farthing. I LOVE alternate history and mysteries, so this book (about an alternate 1949 in which the Brits made peace with Hitler) is right up my alley. And there are apparently more. (Of course there are.) Here's a list of her books with a picture of her rocking a fedora like Kelli Stanley's Welsh cousin.
By the way, the story of the day is Scalzi's HILARIOUS, Hugo-nominated fantasy parody "The Shadow War of the Night Dragons: Book One: The Dead City: Prologue." Here's a link to it.
