Wow, I liked this very much!!! Time-travel, child!Sev, Harry trying to save him, etc -- lots of good parts. The idea that the future wizards could have created Voldie by their botched return is chilling, and Ginny's obsession over Harry is just disturbing. Liked Hermione's characterization, esp. the idea that she would have left herself a note.
Just a note that the formatting of the fic (black type on dark grey background) makes it very difficult to read. If I hadn't been intrigued by the summary, I wouldn't have bothered to copy the fic into Word for reading, and would have simply hit the "back" button.
