A Dragon's Mate.

Harry thought that he the perfect life. Friends who cared for him, mother and father-like figures and people to teach him things, but it was not all it seemed.
Harry had snuck into one of the Order meetings and he learns he is being betrayed and used. Lily and James Potter are not his parents, he has had his magic bound and a marriage contract created.
Harry joins those he was meant to from the start and together they will make the light regret what they had done to him.
Will include Yaoi and Mpreg.
