Summary
When Senior Auror Harry Potter is strongly encouraged into volunteering for an experimental Ministry time-travel program, he plans to spend his year in the past sabotaging Tom Riddle’s rise. Heroic, right?
What he doesn’t expect is a timeline where Tom, upon opening the Chamber of Secrets, finds piles of gold instead of a basilisk and becomes a billionaire. He still has plans for power… but they’re not exactly hostile.
Harry decides to lay low for the rest of the mission. Except… laying low has never exactly been his strong suit, has it?
Or:
Tom is handsome, young, rich, dangerously intrigued, and doesn’t take no for an answer. Also, handsome.
Harry is forty, poor, annoyed, and just wants decent crisps for once. And what does Tom Riddle want from him?

Summary
Harry and Draco were trapped in 1940s Hogwarts with young Tom Riddle, and he was nothing like the monster from their history books. He was charming and brilliant and dangerous in ways that made their skin crawl. Every day under his watchful eyes, they found themselves drawn deeper into his web and closer to each other than they’d ever meant to be. The lines between enemy and ally blurred until they couldn’t tell which was more terrifying: Riddle’s growing interest in them, or the way they’d started to need each other to survive.
***
Or what Harry and Draco thought they knew as history was only half the truth.

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
Be on guard, my Lord, writes Abraxas Malfoy, the new transfer student intends to kill you.
Except Abraxas has terrible penmanship, and kill and kiss look awfully similar in shoddy cursive.
Naturally, things escalate. A lot.

Summary
Somehow, Harry is a Parselmouth. Keeping it secret takes a toll on him, but he doesn't know what else he can do when his parents are so afraid of snakes.
Tom Riddle is a Parselmouth, one who's spent decades alone and yearning for another of his kind. Once he discovers Harry, he's not about to let him go.
Anthology containing:
Evidence of Absence
Tom can't say that his life as Hogwarts's Professor of Defense Against the Dark Arts is perfect, but he's content with it. Then Albus makes a fairly innocuous request of him- to investigate a student who is sneaking off to the Forbidden Forest- and Tom's whole universe changes.
Natural Selection
Tom has discovered Harry is a Parselmouth, which to him signals the end of his loneliness in the world. For Harry, it’s the beginning of a struggle with his family and a terrifying happiness that he believes he could lose any second.

Yet somehow he still ends up attracting Tom Riddle’s attention.
