10k+Harry Potter and the Prince of Slytherin » by The Sinister Man Harry Potter was Sorted into Slytherin after a crappy childhood. His brother Jim is believed to be the BWL. Think you know this story? Think again. Year Four starts on 9/1/20. NO romantic pairings prior to Fourth Year. Basically good Dumbledore and Weasleys. Limited bashing (mainly of James).
