Well, it's hard to say no to an endorsement like that. And I know lots of people love it. You've certainly made me more excited to give it a go.

I don't think reading it would mess with Doctor Who - it's a wonderful work of art in its own right (and one of the very, very few books that reliably makes me cry) - but I think you would undoubtedly notice all the things Moffat has consciously or unconsciously taken from it. But I don't think that's a bad thing.
I think that's part of why I've been putting it off, lol. I can tell it will be an emotional investment!
