Whispers in the Castle (джен)

While trying to escape from Dudley and his gang, nine-year-old Harry Apparates himself to Hogwarts instead of the roof of his school. Thrilled by his magical surroundings and the lack of vindictive Dursleys, Harry decides to blend in amongst the students so he can stay in the castle forever.
Meanwhile, Severus tries to make sense of a new, tiny first-year whose name he can't quite place.
