Wrath of time (rewritten)

Harry lives a miserable existence, he knows that his wife gives him love potions and he accepts that but then one day a woman appears to him in a dream. She says that he needs to back and fix his past to save the future and he wakes up in his fourteen year old body ready to shake up the Wizarding world. Timetravel fic. Not a harem fic (people chose not to read thinking it was)
