I really like this fic, and very much enjoy the lectures that Harry gives to his classes. They are really good at making other ideas known besides the already accepted ones, as in light spells and dark spells, etc.
I hope that you update really soon. That was one hell of a cliffhanger you left the story at!
I wonder, will this Ginny after having Tom removed from her head turn into the Ginny that Harry had fallen in love with in the other world? I know Harry is sort of together with Narcissa but it seems like their relationship is based on sex than any actual feelings. Maybe Harry will even end up with Luna since they have a good relationship here!
