(Hi I'm going back through your reviews looking for stuff you liked last year because you have great taste and I need recs.) Anyway, just dropping by months later to say that one of the things I think is interesting in re: Faceless Man and the fantasy texts is that not only are Faceless and Peter both fans, so is Aaronovitch, and so, I think, are a large portion of his readership. Faceless' bookshelves - Tolkien, Alan Garner, Susan Cooper, this is my bookshelf aged 7-17 (and not too dissimilar to my current bookshelf). And I bet I'm not alone among Rivers of London fans. I think that's a conscious, deliberate part of Aaronovitch's thinking - deliberately taking "sacred" texts (also very British and white texts) and giving them to the bad guy, forcing his readership to re-examine their relationships with those books and the ways their thinking might align with Faceless.
