Harry Potter and the Time Travel

This story is set at the end of Deathly Hallows and back to the beginning of the series. I know this has been done before, but this is my version, and my time frame. Lily and James Potter are alive, and plenty of good ole fashioned bashing! Time travel! Slow beginning though...bear with me. Please don't forget this is FANFICTION, so I can write my characters and such how I please.
