For the Devil to Dance Again [tomarry]

Everyone knows the story of the Boy-Who-Lived, Ryan Potter. But most don't know the story of his younger twin, Harry, who's lived the fourteen years since You-Know-Who's defeat in the shadow of his brother.

Sorted into Slytherin and an outcast among his own family, Harry is determined to make a name for himself apart from his brother's fame. The gap between him and the Potter's is growing ever larger, and Harry couldn't be more pleased. He's a prefect, seeker on the Slytherin team, and one of the best students in his year. With his O.W.L.'s coming up, his plans for the future are finally taking shape.

As he enters his fifth year, Harry is immediately drawn to their new Defense Against the Dark Arts teacher, Professor Tiberius Rowle. The mysterious pureblood is skilled at magic in a way Harry didn't know was possible, and he yearns to know more.

Professor Rowle begins to mentor Harry, and draws him deeper into the world of magic than Harry has ever explored on his own.

But Rowle keeps many secrets, and as Harry slowly discovers them, his life will change forever.
