Agree on VERITY, it was great. As for BOOK THIEF, I barely completed it - for some reason I didn't like it. I do look forward to the film, though. Weird!
Yes, I would go and see the film too.
I think maybe because a big part of what bugged me was the style, which I found rather arch, but that won't be a problem on screen. I mean, the plotting was great, and I'd love to see some of the characters brought to life.
Whereas if they made a film of Codename Verity I'd probably hate it because chances are they'd cast at least one character wrong and it's the kind of book where you care about the characters so much they become part of you forever.
