The Shadow of Slytherin

After another resorting ceremony, Harry's life seems to have turned upside down. He is literally in the House of the Enemy; Harry Potter is a Slytherin. This puts him at much unease since there have been many Death Eater attacks, and even worse, he is sleeping in the same room as the relative of the enemy himself. Maybe Slytherins aren't as they seem... or is it just their charm that is distracting him... And distracting he is indeed.
