Tom Riddle's plans fall through when Ginny Weasley loses his diary shortly after starting her first year and it is found by one Luna Lovegood. A series of bizarre conversations follow. Luna? - Yes Tom? - I've been giving this a lot of thought...and I believe you may be insane. (Not crack. I repeat, not crack ! Plot takes a few chapters to appear but it's there)

When Voldemort died at the Battle of Hogwarts, nothing had prepared him to reawaken as Tom Riddle circa 1943, rid of his madness but left with a gnawing sense of defeat. Things may have gone wrong the first time around, but Tom vowed not to let the course of history run unchanged. He could do better, and this time... no one would stop him.

AU. The Sorting Hat doesn't just let the Sword go when it falls on Harry's head in the Chamber, but also Sorts him again, this time into Slytherin. Harry is furious and terrified, and the adults aren't helping much. COMPLETE, sequel to come.
