A popular one is 'Harry Potter: Juvie Years'. It shows Harry's life in juvie and how his magical abilities start to manifest in strange ways. For example, he accidentally makes the lights flicker when he's angry. The story also has a sub - plot about a mysterious figure who seems to be watching Harry from the shadows, and it keeps you guessing as to who it might be and what their intentions are.
Well, there's 'Harry's Juvie Revelation'. In the beginning, it seems like a typical story of Harry in juvie, but then it takes a sharp turn when it's revealed that Harry's time in juvie was all part of a prophecy. He was meant to be there to learn certain life lessons that would make him a stronger wizard. This twist completely changes the perspective of the whole story and makes it a very interesting read.
Maybe it's about Harry Potter being framed for using dark magic in a way that violates the wizarding laws. As a result, he has to go to this 'juvie' place. In there, he discovers that there are other kids who have also been wrongly imprisoned. He then uses his skills and the loyalty of his friends (who might try to break him out or help him legally) to fight against the unjust system.
One great Harry Potter fanfiction is 'The Life and Times' by Jewels5. It delves deep into Lily Potter's life at Hogwarts and her relationship with Severus Snape. It offers a new perspective on the events that led to the Potter family's fate. Another good one is 'Manacled' which has a very interesting take on the post - war wizarding world and Hermione's journey in it. There's also 'After the Battle' which focuses on how the characters heal and move forward after the final battle against Voldemort.
There are fanfictions where the bond between Harry and Lily is explored through time - travel scenarios. In these stories, Harry might get to meet Lily in her own time and they could form a special connection that helps him understand his family history better. This can lead to some really interesting character development for Harry as he gets to know his mother in a more personal way.
One great fanfiction could be 'Lily's Legacy'. In this story, it explores the bond between Lily and Harry in a really heart - warming way. It might show how Lily's love continues to protect Harry even in different magical situations. Another is 'Harry and Lily's Unseen Moments' which delves into some of the imagined interactions they could have had if Lily had survived. It gives a sense of a mother - son relationship that was cut short in the original series.
I also recommend 'Harry and Fleur: An Unlikely Alliance'. This fanfic starts with a rather forced alliance between them due to some unforeseen circumstances in Hogwarts. As they work together, they discover new sides of each other. It's a long - form fanfiction that really takes its time to build up their relationship.
Hermione would likely be there. She's Harry's best friend and would not let him be in juvie alone. She'd probably be trying to find a way to get him out legally, researching all the laws and loopholes. Ron might also show up, being another one of Harry's closest friends. He could be the more impulsive one, thinking about breaking Harry out rather than going through the proper channels. Dumbledore might also be involved in some way. He has always been a guiding figure for Harry, so he could be working behind the scenes to ensure Harry's safety and find a way to clear his name.
I've heard of a paraselenic Harry Potter fanfiction that focuses on the Forbidden Forest. The paraselenic influence makes the forest even more mysterious. There are strange lights and new, moon - related magical beings. Harry and his friends have to navigate through this new and dangerous version of the forest, which makes for a really exciting read.
One great 'Ascension' Harry Potter fanfiction could be 'The Ascension of Harry Potter: A New Path'. It often features Harry developing unique powers and taking on a more powerful role in the wizarding world. Another might be 'Ascension's Call' where Harry is guided by an ancient magic towards a greater destiny. There are also some that focus on Harry's ascension in terms of his social standing within Hogwarts, like 'Ascension Among Peers' which shows him rising above the petty rivalries and becoming a true leader.
One good Harry Sirius Potter fanfiction is 'The Bond Beyond Blood'. It explores the unique relationship between Harry and Sirius in a very heart - warming way. It shows how Sirius could have been more involved in Harry's life at Hogwarts if not for certain circumstances.
