by The Pessimist Prophet reviews
After breaking free from his diary, the sixteen-year-old Tom Riddle decides to dethrone both Lord Voldemort and Albus Dumbledore. Armed with ruthless cunning worthy of the heir of Slytherin, he manipulates the youngest generation of wizarding Britain, but also has to flee his one great weakness: the soul-crushing apathy that makes his very existence feel meaningless.

Harry Potter and the Irrational Odyssey
by ElizabethRobinThales reviews
The Dark Lord has been vanquished. Harry has seemingly won; he holds control of the Philosopher's Stone, the Line of Merlin Unbroken, and the Elder Wand, and has begun laying the groundwork for a global paradigm shift in the nearish future. But all may not be as it appears, and the fate of Reality Itself hangs in the balance. A sequel to Harry Potter and the Methods of Rationality.

Tom Riddle and Conflicts of Interest
by user1444 reviews
This is based on my interpretation of the Tom Riddle portrayed in Harry Potter and the Methods of Rationality. I loosely follow the story and facts laid out by HPMOR but I do make a lot of changes, large and small.
