True Snakes.

Harry Potter had been lied to all his life.
It turns out that he is not the son of Lily and James Potter, but the lost/stolen son of Lucius and Narcissa Malfoy.
When Harry finds this out he will learn that there are more truths that has not been told to him, and when he figures it out he will join his family, where he will find true love.
With his new family and new love to help him he will show those who lied to him, who he truly was meant to be.
