Harry Potter and the Price of Truth

Summary:
The Boy-Who-Lived is Neville Longbottom. Everyone knows this. The child who defeated You-Know-Who, famous since he was one year old.
Hadrian Vale doesn't know any of that. He's got a scar that won't fade, a name that isn't really his, and a habit of making impossible things happen when he's angry.
Then a letter arrives at his orphanage addressed to Harry James Potter. Turns out that's his real name. His parents were murdered. And he is a wizard who can do magic!
Except his parents died the same night as You-Know-Who was defeated, and no one can tell him what killed them. Every answer he finds raises more questions.
Harry just wants the truth about his family. He doesn't want to be part of some war he never knew existed or a piece in anyone else's game. But the more he uncovers, the less choice he seems to have.
