I didn't make a prediction this year because I haven't had time to read enough children's books, but I do have half a dozen books out of the library, making them a sort of shortlist. And Gaiman's book is among them.
I haven't read it yet. Obviously it will now go to the top of my reading list.
I'm getting closer to predicting the winner. This year the book's on my short list; last year the book I chose for the Newbery, Brian Selznick's The Invention of Hugh Cabret, won the Caldecott. Maybe next year's the year I'll ace it.
