Well, it could be about Harry Potter seeking Amelia Bones' help in solving a mystery within the wizarding world. Maybe a new dark magic threat has emerged, and Amelia Bones, with her expertise in the Ministry of Magic's law enforcement, teams up with Harry to get to the bottom of it.
There could be a group of dark wizards who are working together to bring chaos to the wizarding world. They target Amelia Bones because of her position in the Ministry and Harry Potter because of his fame. This group, with their evil intentions and powerful dark magic, would serve as the main antagonists in the fanfiction.
One possibility is that they meet during a Ministry event. Harry is there because of his status as the 'Boy Who Lived' and Amelia Bones is representing the Department of Magical Law Enforcement. They strike up a conversation about the future of the wizarding world and how to better protect it from the remnants of Voldemort's followers.
A power - hungry wizard within the Ministry itself could be the antagonist. He sees Amelia Bones as a threat to his rise in power and also dislikes Harry for his influence among the wizarding community. He spreads false rumors about them and tries to get them in trouble, all while trying to further his own political agenda.
She is often portrayed as a strong and capable witch. She's shown to be fearless in the face of danger, especially when it comes to dealing with dark magic and dark wizards.
Amelia Bones is a high - ranking official in the Ministry. She is part of the wizarding establishment that Harry Potter often has to interact with. Her role could be crucial in times of upheaval, like during the return of Voldemort. She might offer her expertise or resources to Harry and his friends in their fight against the Dark Lord.
One common theme is mystery. Since Amelia Bones was involved in investigations in the wizarding world, fanfictions often use her to uncover secrets related to Harry Potter or the overall wizarding world situation. Another theme is mentorship, as I mentioned before, where she imparts her knowledge to Harry.
There isn't really one 'best' author as different readers have different tastes. However, some authors who have a large following for their 'Harry Potter' fanfictions might also do a great job with Amelia Bones. They usually have a good understanding of the overall 'Harry Potter' universe and can integrate Amelia Bones into the story in a seamless way. You might want to look for authors who have received a lot of positive reviews for their stories involving similar themes or characters.
One possible plot could be that they meet during an investigation into dark magic. Harry, with his experience, and Amelia, as a powerful figure in the Ministry, start to respect and then fall for each other. As they work together, they face challenges from dark wizards who try to stop their investigation and their relationship.
