Can you help me find this Harry Potter fanfic?

I cannot for the life of me remember the title to this fanfic i want to read. I'll try to give you the best summary that I can: Harry goes independent from Dumbledore. He trains in combat, and fights under an alias along side the Order (blonde, the order thinks there're two of him), before Minerva finally figures out its him by watching him teach the DA. Has one or more (cant remember) animagus forms, one of which is a black panther with green eyes, i think. Im pretty sure it Harry/Ginny, but not positive. Any help would be appreciated. Thanks!
