The Light and Dark Inside Us

AU: Harry never had an Aunt Petunia. There was no blood-relative to carry on his mother's spell. But the best protection is anonymity, and no one would expect the vanquisher of the Dark Lord to be living in a back alley with the rats. Fighting tooth and nail—kill or be killed—Harry raised himself. He is not sweet. He is not innocent. And his time at Hogwarts will show that.
