Doing the impossible isn't something new for Harry Potter. Going back in time he hopes to change history for the better, hopefully he wont muck it up to badly. Cant say for sure with that Potter luck of his. (M rating as a precaution)

Doing the impossible isn't something new for Harry Potter. Going back in time he hopes to change histoy, maybe with his friendship with Draco and the realization that Ron isn't as trustful will be enough. Then again since when has Harry's plans ever gone as he wanted them. (M rating as a precaution)
