My goodness...THAT was a rollercoaster of a ride! Any story that pairs Harry and Severus together in any fashion that they have a connection (friendship or otherwise) will always grab me, and while I've never been a Percy fan you've entirely won me over here. Mysteries...I SO love mysteries! I had to stop a couple of times to deal with household matters, and it was frustrating to walk away each time.
That plot was so intricate and brilliantly executed and I lost count how many times I was on the edge of my seat. It was so easy to understand Snape's frustration at being out of the loop because I was frustrated too! I am in awe of authors who can wrangle the myriad of characters that you wove into this and keep them in character. *mind boggles*
That was a really phenomal Christmas present for midnight_birth, lucky person. Heck, we ALL got a fabulous present with this story.
