Of Kings, Of Pawns, and Of Men

Harry wakes to find that he is now in Tom Riddle's body. The Dark Lord? He happens to be doing an unfortunately good job of impersonating the Boy-Who-Lived. Dumbledore's disappeared, and Voldemort doesn't hesitate to let Harry know he makes a weak replacement. Naturally, Harry has no choice but to prove him wrong. Also: Grindelwald escapes Nurmengard and a new war ensues.
