Harry's life post final battle isn't what he expected it would be, and then he dies, just like that. He gets a second chance but forgets to read the fine-print, and ends up somewhere in the distant past while his body suddenly looks quite differently. Now he's stuck as a teenager attending Hogwarts again, where he encounters an old enemy, and surprise, it's not Tom Riddle. All Harry has to do now is survive long enough to build a life for himself that's actually worth living. Harry Potter/Tom Riddle
