In this scenario, it would be a very strange and out - of - character event. Hermione's parents are muggles, and Hedwig is Harry's owl. Maybe in the fanfiction, there could be some sort of misunderstanding. For example, they might think Hedwig is a dangerous creature and capture her to protect Hermione. But this would also cause a huge rift between Harry and Hermione as Hedwig is very important to Harry.
One possibility is that Hermione manages to talk some sense into her parents and they release Hedwig. This would require her to explain the importance of Hedwig to Harry and the fact that she is just a normal owl in the wizarding world.
I'm not sure of a specific fanfiction titled exactly that, but a lot of fanfics in the Harry Potter universe might have a scenario where Hermione looks after Hedwig. You could search on platforms like Archive of Our Own. Just type in 'Hermione and Hedwig summer' and you'll likely find some interesting reads that could potentially be what you're looking for.
In some fanfictions, the Order might kidnap Hermione because they believe she has some sort of dangerous knowledge that could fall into the wrong hands. They think that by taking her into their custody, they can protect that knowledge and keep her safe from the real enemies who might want to use her.
At first, Hermione would be shocked. But then, she would quickly compose herself. She could play along with Draco and Blaise for a while, pretending to be compliant while she actually gathers information about their motives and the place where they are holding her. She might also try to turn them against each other by highlighting their differences in goals or personalities. Given her intelligence, she would surely come up with a clever plan to get out of the situation.
For Hermione, her character would be fighting against this unjust situation. She would be using her wits to try and escape. Meanwhile, Draco and Zabini may start to have second thoughts as they see Hermione's strength and determination. Maybe Draco's motivation changes from self - interest to a more complex mix of respect and fear for Hermione.
Hermione's parents in fanfiction can be portrayed in various ways. Some fanfiction authors might give them more magical abilities or knowledge than they actually have in the original story. This could be to create more interesting plotlines. For instance, they could have a long - lost relative who was a powerful wizard and this connection is explored in the fanfic, which in turn affects Hermione's journey in the magical world.
She would be devastated. Hermione is a very emotional person deep down. She might isolate herself at first, not wanting to talk to anyone, even her closest friends like Harry and Ron. She'll probably go through a phase of denial, not believing that her parents are really gone.
Well, Hermione might use Hedwig to send secret messages to Harry and Ron. Since Hedwig is Harry's owl, she could be a link between them during the summer when they're apart. Maybe Hermione discovers some new abilities of Hedwig, like the owl can sense danger in a different way.
