When I was a little kid, I LOVED watching old b/w movies on Sunday afternoons. Especially, the private eye flicks and other murder mysteries. They were my second favorite genre, after science fiction!
And, that's why I equally love the fact that the "interior" of the magical book was also black and white. It gave a true feeling of "retro-ness" to the unfinished story that everyone was forced to experience.
As for the book, itself? There are only four words that can adequately describe it. And, those four words are: a real "Paige Turner!"
Sorry; I couldn't resist.
