It is so far in my life the best story I have consumed in any media. I remember when I finished it I couldn't really enjoy movies or other books for several months. Every story felt shallow afterwards. Took a long time for me to forget Worm and to start enjoying other stories again.
You may well have already seen it, but http://www.hpmor.com/ was even better, IMHO. It was there that I saw my first recommendation for Worm.
Thanks, I have my doubts but I'll definitely give it a read.
