Definitely not. Fanfiction should be a medium for creative and positive storytelling. This kind of description implies a violation of a character's rights and is not suitable for reading.
There are many positive and well - written fanfictions out there. We should focus on those that uphold values like respect and equality rather than ones with concerning themes. So, I won't be able to give details about this particular fanfiction.
One plot idea could be a situation where Hermione is magically forced on her knees in a dangerous spell -binding scenario. Maybe she's in a trap set by dark wizards and has to use her wits from that position to escape. Another could be a more emotional plot where she's forced on her knees as part of a false accusation, and she has to prove her innocence while in that vulnerable state. A third idea is that she's forced on her knees during a battle of wills with a powerful, manipulative character, and she must resist the mental pressure.
The theme of resilience can be shown when Hermione, despite being forced on her knees, refuses to give in mentally. She could keep her mind sharp, looking for any weakness in her captor's hold or in the situation. For example, she might use her extensive knowledge of magic to start formulating a counter - spell or escape plan right away.
One possible reason could be that she is facing a powerful dark wizard who wants to assert dominance over her. Maybe the villain is trying to break her spirit as she is known for her strong will in the original story.
There would be a sense of humiliation. She is used to being respected for her knowledge and abilities, and this situation goes completely against that. It would be a blow to her self - esteem.
Such fanfiction is completely inappropriate. Hermione is a well - loved character from the Harry Potter series. Subjecting her to non - consensual and sexually explicit scenarios is against the values that the series promotes. Fanfiction should be positive and in line with the general tone and ethics of the original work.
One possible plotline could be that her friends, like Harry and Ron, discover her situation through some clues she managed to leave behind. They then use their magic skills and knowledge of the wizarding world to infiltrate the place where she's being held. Another could be that Dumbledore, with his vast wisdom and power, somehow senses her distress and sends a team of trusted Order of the Phoenix members to save her.
I haven't read this story in detail. But generally, Tim Winton is known for his vivid descriptions of Australian landscapes and complex human relationships. Maybe in 'On Her Knees', he explores themes like personal struggle, family dynamics or the connection between a character and the place she's in.
One consequence could be that she is forced to perform dark magic against her will. This would be a huge moral struggle for her, as Hermione is a firm believer in the light side of magic. It could also change her perception of herself and her magic abilities in a very negative way.
