I like this, my favourite HP fics at the moment seem to be manipulative-Dumbles! More, please.
DH was a hell of a disappointment but I think many were ready for this, JKR's writing style took a major hit after GoF with regard to character development - the additions of Luna, Ginny and Neville to the core threesome seemed rushed and we never learnt much about them that wasn't already given by GoF - except that all of a sudden Ginny was very MS-ish (grr!)
This story seems to fit in more with JKR's given plot history (as in it fits the events we have already read about) and it does it in a believable manner.
Keep up the good work!
