Awesome story I do love Harry grows a backbone story and the connection with Riddle is so open to interpretation. In this Harry has no support when his name is pulled and in the process of trying to calm himself he retreats to his mind where he finds that his magic has placed a large barrier against something. Upon pulling down the barricade he realizes that the darkness does not have to be feared. He also finds out that over the years he has been using a lot of magic on a daily basis for the blockade and now that magic is accessible to him. He slowly realizes that he is not a light wizard and the there is more to Moody then he thought. He confronts the deatheator in disguise and asks to be taken to Voldemort. The first story shows Harry's trip to being a dark wizard and his alliance and help in restoring Voldemort. In the second story the relationship between the two really begin as they start to gather allies. Harry's character grows with the story he is strong, mature and ready to seek revenge on those that betrayed him and stand at the side of the only one who can match him. The story is by two different authors but definitely worth the read.
