Dead Wizard walking

AU - The Death eaters attack Diagon Alley on the day of Sirius's will reading. Harry is badly wounded but is 'saved' by the Lovegoods'. He wakes from a coma to find he is not quite himself... Will he be able to overcome these drastic new obstacles placed in front of him, all while fending off Voldemort and his death eaters? A Harry / Luna Fanfic. (P.S. Contains Vampires :/)
