I found this totally by accident; we both have Eiri/Tohma listed as an interest and I happened to click. Then I was glancing over your fic list and found Lucius/Draco and figured I'd read it.

God. GOD. I am so glad I did, I can't tell you. This might be old, but it's brilliant and utterly gorgeous. You did an amazing job of making it wrong without being wrong, and right without actually ever being appropriate. Amazing work.
