Love from the abused!

REVISED! Harry is a six year old and has already had enough of life, what happens when twenty-five year old Severus finds out the women he "thought" as a his sister son is being abused not only mentally, but sexually and physically but the most shocking is what happens what everyone finds out that harry isn't really a Potter (Harry&Draco)(Severus&Tom)(Lucius&Narcissa)(Sirius&Remus)
