The Dragon Unleashed

This is a wrong Boy-Who-Lived fanfiction, in which the Longbottoms happen to be the ones Voldemort went after that fateful night of Halloween. Neville's grandparents died saving him and he survived the Killing Curse. Harry with a greater destiny than canon version. Good snape. Evil Dumbledore. Egoistic Longbottoms. Harry/Fleur, but pairing doesn't start till sequel.
