Oh god, I came back to reread my fabulous gift while I wake up a bit this morning, and see that my comment apparently didn't post -- I'm SO SORRY I didn't realise that sooner, mystery author, I have no clue what happened there. My LJ comments seem to be posting twice at the moment, so maybe it's stealing them from IJ :( Gah.
Anyway, I will recreate as best I can without making you wait any longer than I have to. I absolutely loved this, and I want to thank you again for Moody fic to start with, as that was just what I wanted for my fic. It was a great thrill seeing that to start with, and you more than gave me everything I wanted from a Moody fic! I love the politics, the history and the world building you added (that really make it yours!), the closed, secretive feeling of the conversations and plotting, the insights into the Auror's world as well as that of the Order, and like others have said, of course, the relationship between the two.
I love how this feels so real, the detail and the realistic conversations make them all into fully three dimensional human beings and your very natural dialogue is a beautiful thing that I not only want to squee madly over but also brings its own feeling of being involved in their world -- it's like genuinely listening in on their conversations! I really love that.
There's so much here that I could never come up with myself in a million years, not being a world-builder or one who is inclined to think things through in this amazing level of detail, so THANK YOU so much for creating it for me. You are an absolute star, mystery author! And I apologise once more that you had to wait so long for this comment, I'm kicking myself at not realising sooner :(
