Heh, I've done that - ruined my eyes reading fanfic, I mean. Usually late at night when I'm already two hours overdue for bed. I apparently don't have the willpower to stop in the middle of a story and save the rest for later.
*headsmack* Bottom!Snape! I didn't think to include that in the warnings, but I should have. I know a certain percentage of readers finds the idea distasteful. Oh well.
Thanks for reading on in spite of that. And for your lovely comment. I took a few liberties with JKR's version of magic, so I'm glad it came across as imaginative rather than heavy-handed.
