Summary
Tom Riddle has never done anything he didn’t choose to do. Not the watch on his wrist, not the ring on his finger, and certainly not the prayers. Harry Potter, his best friend since childhood, knows he doesn’t mean any of it. Between them, they don’t keep secrets – not the important ones.
But tonight, when Tom sneaks over at midnight, he finds Harry in the middle of rolling a secret. In a fit of spite, he takes the blunt and smokes it for himself.
He gets very, very high.
And it turns out some secrets are more important than either of them ever knew.

Summary
Harry Potter died saving everyone. But the world kept turning, and something even worse came. Death drops him off in snowy 1938 London to stop the world from burning once more.
Just one problem. He's got paws instead of thumbs.
In the garden of Wool's Orphanage, Tom Riddle's first friend is a tiny snake. Billy Stubbs kills her with a trowel. Tom takes his revenge - brilliant and vicious, but he's so desperately outnumbered that when his bullies corner him, Harry can't help but intervene. A debt Tom repays by designing a collar that can bind a Grim.
Sometimes the road to redemption is paved with ash.
— a.k.a. a dark time-travel romance following Tom's journey from boy to man, Harry's struggle between justice and mercy, and whether caring can redeem someone - or if it only makes them worse.

love in a different shape (looks a lot like dying) by improbas

Summary
“Immortality is a funny thing,” the boy says. His tone is light and yet Tom senses the chastisement in it. “There are those who deserve it, those who do not, and those for whom it is nothing more than a curse.”
“I deserve it,” Tom blurts, immediate and without hesitation. He is not normally so impulsive, but the boy’s attitude – serene yet loaded with insult – pricks him sharply.
The boy does not take offense. Instead he merely asks: “Which one do you think I am?”

Summary
At eleven, Tom Riddle is dead set on flying and deathly afraid of heights.
At seventeen, he is a Hogwarts dropout and a Dark Lord rivaling Grindelwald.
At twenty, he is barely a wizard, robbed of his magic and wracked by Muggle illness. A simple case of consumption shall end him, unless Harry unravels Riddle's mysteries once and for all.
(Or: An AU where Tom and Harry grow up together, fight a war, twist a prophecy, break Quidditch, and fall very badly in love, though perhaps not in that order.)

Summary
It's been nine years since the Battle of Hogwarts and the wizarding world has been wiped of almost all criminals, thanks to the incredibly hard-working Auror, Harry Potter. With one last remaining Death Eater to catch, they are on the cusp of peace at last.
That is, until Hermione brings reports to Harry concerning a murderous snake whom she believes has something to do with the deceased Dark Lord. She thinks it could be the seventh part of Voldemort's soul, created because he did not know about the (now destroyed) Horcrux that was in Harry. Seven Horcruxes, not seven parts.
Harry finds the snake and feels compelled to assuage some of his survivor's guilt by making the man suffer. He recreates the resurrection ritual, but this time, with a crucial alteration to the ingredients: the flesh of a servant. Without it, the Dark Lord Voldemort has no magic. Harry secretly takes the man prisoner in his home, wanting to hurt him, to force him to divulge where his last Horcrux is, but things begin to rapidly fall out of his control.

Summary
Harry Potter was a perfect symbol of the Light. Cursed at birth by a spell that had affected so many of his generation, he overcame his inherent nature, depending on his faith to eventually save the world. He became a beacon of hope, evidence that anyone could be redeemed. Even ten years after the events that had tested the very limits of his willpower, he continued his work. He was determined to find proof of miracles—to see that the Light looked over the rest of the world as it looked over him.
And he eventually found what he was looking for.

Summary
One would think traveling 52 years into the past would allow Harry some much desired anonymity, but unfortunately the malfunctioning Triwizard Cup spat Harry out on the quidditch pitch in the middle of a game. There's no lying about his provenance while a shiny plaque on the base of the Cup announces to everyone he is 'Harry Potter, Hogwarts Champion, 1994.'
Swept up by the ministry and sworn to secrecy by the Unspeakables, Harry is left to navigate the past on his own. Good thing his great-grandparents are willing to take him in - even if they're a little more into blood purity than Harry had expected - and Hogwarts is willing to welcome him back - even if he's a novelty to everyone as the time traveling Champion.
At least Harry will have the familiarity of Gryffindor Tower to ease his homesickness. Or he would, if the sorting hat hadn't put him in Slytherin, where he's forced to share a dorm with none other than Tom Riddle.
---
In which Harry is determined to prevent Voldemort's rise, even if he has to stalk, bribe, threaten, and marry Tom Riddle to do it.

Summary
When Petunia first abandons Harry to the cupboard under the stairs, a paroxysmal reaction of magic sends the infant back through time to the relative safety of 1963. Recovered from the site of a magical hailstorm in Surrey, he is adopted into the Potter family.
Or—
Harry Potter is entering his sixth year at Hogwarts. With less than satisfactory OWL results and a war brewing just outside the school walls, he has plenty to contend with . . . the last thing Harry needs is to catch the attention of the rising Dark Lord.
