Oh, I really, really liked this. The way you wove politics, humor, the sixties, and the Harry vs. Voldemort mystery together was brilliantly seamless. I loved the easy way they fell into the relationship, Lucius' jealousy, the way you still managed to introduce the concept of a Horcrux into a non-magical story. Really fantastic!
Also, your Hermione? I was laughing my ass of at her every time she made an appearance. I even liked your Ron, and he is not my favorite character.
I can tell that so, so much heart went into writing this. It shows! Totally going to rec this on my IJ now :)
