Gunther and Laufeia (a Harry Potter Fan-Fiction)

Gunther thought he was perfectly normal. He went to a normal school and had a normal life. That is untill his parents tell him that he was actually adopted. It gets even weirder for him when an owl brings him a letter telling him that he has been accepted into a place called Hogwarts. What's even weirder is that he actually ends up being the long lost twin brother of Harry Potter. He goes to Hogwarts and ends up being sorted into Slytherin where he meets and falls in love with a girl named Laufeia who is actually the daughter of the dark lord. Laufeia plans on killing Harry to avenge her father. Will she succeed; or will Gunther stop her?
