Summary
Harry Potter, Auror for the Ministry of Magic, is assigned an international case with MACUSA as an 'expert consultant' - even in 2002 people want Harry Potter to turn up to things based on events in 1981 and 1998 - but whatever these supposed Death Eater sympathisers are doing in Muggle America, doesn't match at all what the Ministry, or MACUSA know about them. These must be something else here...
Cross posted on FFN, will cover multiple years, from 2002 (when Thalia/Luke/Annabeth go to Camp Half Blood) and 2007 onwards (when The Lightning Thief occurs), canon characterisations (no Fem!Harry or demigod!Harry, and Percy is younger than Harry, etc.)

Summary
Sick of the Dursleys and resolved to missing his few friends if it means getting away from the people of the Wizarding World and their nosy whispers, Harry gets the idea to leave it all behind for a while, just a bit, just for a rest. Like a camping trip, except he’ll take enough provisions for a year or so...maybe some plants, seeds and things for a little garden. Maybe some time away from the things that weigh him down will help the constant highs and lows he’s been feeling for a while now. Just a little break.
(Or, the one where Harry says TTFN and takes himself off on an indefinite vacation and upsets a few very careful plans.)

Her Own Kind of Bravery by twen25tyfive

Summary
"But time, ironic and sometimes cruel, is the most precious and worthwhile thing to invest in. Like white wine, the longer it is aged, the rounder, smoother and more fragrant it becomes. Each person's journey is different, it's never too early and it's never too late to start something. And the combination of daring to try and being reckless and the clarity of mind. Completion is finding balance, perhaps?"
It'd be great if you had time to read the whole thing because there are many small details mentioned at the beginning that connect to the logic later on. But if you just want to read the exciting part, you can read from chapter 20, in the numbering order currently here is chapter 21: "There's no cure" (My story consists of four parts: The Yule Ball, The Wedding, The Proposal and The Honeymoon Phase. So the order of the chapters may be different from the title)

Summary
❛ Do you think, just because I am poor, obscure, and ugly, I am disgusting? ❜
❛ Now you twist my words. Because never ever have I said you are ugly or disgusting, Mira. ❜
⚤ 𝚜𝚝𝚛𝚊𝚗𝚐𝚎𝚛𝚜 𝚝𝚘 𝚕𝚘𝚟𝚎𝚛𝚜
Mira Zyvia Weles lived a simple life in her small hut on a mountain, all alone. It wasn't a magnificent life, but it was hers.
In an unfortunate and odd turn of events, she stumbles against a body. Although it looks so, it isn't dead.
She drags it to her hut in hope of helping. She would never forget that ashy skin that she found to be covered with lunar scars; bitemarks and scratches scraped into the mysterious boy's body like a wood carving.
She then learns it is no fairy tale but a horror story, her home haunted with worse than a specter.
She just has to weather this winter and soon Regulus Black would turn into dust like everything else. A shadow on her memories and a touch of ghost against her skin.

A girl. A tower. A broken spirit.
A boy. A sharp tongue. Cruelty dressed as indifference.
A jump. A fall. Silence.
A grave. A red rose. No body.
Death. Regret. Time.
But time—
Time, time.
Can it break it all?Can it rewrite the end?

Summary
Regulus Black knows what his future holds. He will be a good son, a good Pureblood, and a good Slytherin. He will not stray from the path set out for him since birth.
The trouble begins with a bar of Fry’s Turkish Delight—or maybe it begins with a Charms competition, a stick-and-poke in the Prefects’ bathroom, and a Hufflepuff with strange magic.
Or: Pandora Lovegood was born Pandora Trelawney. When her inconvenient magical gift puts her squarely in Regulus Black's path, an unlikely friendship blossoms. The consequences echo past their final year at Hogwarts, follow them to opposite sides of the battlefield, and change the course of the First Wizarding War for the better.

Summary
After her husband is unfaithful and her cookie-cutter perfect world is turned on its head, Petunia Evans Dursley finds herself in her old hometown, full of regrets and feeling that her life has been without purpose. Before she can quietly take her own life, she is given an impossible offer by a long-dead figure from the magical world: return to the past, and rewrite her own history. Seeing it as a chance to make up for her biggest regret, Petunia accepts and finds herself in the middle of a Wizarding war she knew little about, protecting the younger sister she tried to forget by seeking help from the one person in the magical world she knows how to find.
A what-if story beginning in the latter years of the first war against Voldemort, where an unlikely alliance turns into an even more unlikely romance, and the bonds that bloom from it will change the course of Wizarding history.
