I'm reccing a story by Jinko. It's actually a new story and it only has two chapters but it sounds very interesting so I'm posting it up.
Hand of Sorrow by Jinko
Summary:
Inspired by the song by Within Temptation. Harry was taken in by Albus when his parents were killed by Voldemort. He was six. He is raised to be the perfect assassin and has killed Voldemort before his teen years. The real trouble is his followers, which are left over. Not only that, but he's living in Hogwarts without actually having anything to do with the students around him. On his way home one night, he sees someone his own age and is instantly intrigued by him. Over the years, the two form a friendship and then a love while Harry tries to destroy the left over army.
The painful part of it is that the leader of the army is Draco's father.
