Well, 'Hermione's Memory Quest' is also a fanfic you should check out. It not only focuses on her restoring their memories but also shows how her friends, especially Harry and Ron, support her through the whole process. It gives a great look at the friendship dynamics while dealing with this complex magical situation.
I remember reading a fanfic called 'Restoring What Was Lost'. It delved deep into Hermione's emotional turmoil while attempting to restore her parents' memories. The author beautifully described her fears of what would happen if it went wrong. It was a really unique take on the concept as it also incorporated some elements of Hermione's research in the Hogwarts library to find the right solution.
Her parents might be in danger. Since Voldemort was after her, now that they remember her, they could become targets. The Death Eaters could use them to get to Hermione.
One great Hermione and her parents fanfiction is 'The Granger Family Reunion'. It beautifully explores the relationship between Hermione and her parents in a post - war scenario. The story delves deep into how they cope with the changes in Hermione's life due to her experiences at Hogwarts. Another interesting one is 'Hermione's Muggle Roots', which focuses on how Hermione's parents influenced her values and her journey in the wizarding world.
I really like 'Hermione's Muggle Roots'. In this fanfic, the author explores how Hermione's parents' occupations as dentists influence her in a unique way. It's a really heartwarming story that shows how much Hermione values her parents despite the differences between the Muggle and wizarding worlds. There's also 'The Granger Family Bond' which is all about the strong bond within the Granger family and how it withstands the challenges that come with Hermione being a witch.
Often, there's a countdown or a time limit involved. Maybe there's a magical condition that if not met within a certain time, her parents' memories will be lost forever. This adds a sense of urgency to the story. Also, the use of Hermione's own guilt and determination as a driving force for her to keep trying in the face of multiple failures is quite common.
She could also seek the help of very powerful and wise magical beings. For instance, she might journey to find a centaur who is known for his knowledge of rare and complex magic. The centaur could guide her in creating a potion or performing a ritual that would bring back her parents' memories. Additionally, some fanfictions might have her use her own powerful magic in a unique way. Since Hermione is extremely intelligent and magically gifted, she could figure out a way to tap into her own latent power and use it to reverse the charm she placed on her parents.
One great fanfiction on this topic is 'A New Beginning for Hermione'. It shows how Hermione's friends discover her situation and step in to rescue her from her abusive parents. The story delves deep into Hermione's emotional state during this difficult time and how she slowly heals with the support of her friends.
One interesting fanfiction could be 'Mind's Puppet'. In this story, the author creates a really unique scenario where Hermione's mind control leads to some unexpected alliances and plot twists. It's a great read if you like exploring the darker side of magic in the Harry Potter universe.
I haven't come across many (if any) fanfictions with this exact plot. It's a rather extreme idea. In the world of fanfiction, most writers like to keep the essence of the characters intact. But for those who do write about it, they might be exploring the darkest corners of the human (or in this case, wizard) psyche. They could be showing how power, or a wrong turn in life, can lead a character like Hermione, who is known for her goodness, to commit such an unthinkable act.
One great Hermione and werewolf fanfiction is 'The Wolf's Mate'. In it, Hermione has an unexpected encounter with a werewolf and their relationship unfolds in a very interesting way. It has a lot of character development and some really exciting plot twists.
