Serpent in Lion's Clothing

Harry Potter is sick of being treated like a chess piece in the wizarding war. He has been betrayed by those he was meant to protect and he's had enough of it. When he seeks out Voldemort he expects to die, but upon learning new information about the boy who lived he offers the boy another choice. To join his side and end the war, but Voldemort's plans aren't quite what he thought.
