Some fanfictions might be part of a series. So, when you search, don't just limit yourself to stand - alone stories. Check out series that might have a plotline where the Cullens find baby Bella. Sometimes, the build - up and development in a series can be more in - depth and interesting compared to a single - shot fanfiction.
Obviously, the Cullens would be the main characters. Carlisle, as the patriarch, would play a crucial role in raising Bella. Esme would be like a mother figure to her. Edward would also be important, his relationship with Bella evolving from something different than in the original story. And of course, Bella herself is a central character.
There are several places to look for it. Firstly, Archive of Our Own is a great resource. It has a wide range of fanfiction, and you can use the search function to look for 'bella sings for the cullens'. FanFiction.net is also a popular site where you might find it. Additionally, some Twilight - related fan communities on social media platforms might be able to point you in the right direction. However, make sure to respect the rules and regulations of these platforms while searching.
In some stories, Bella could be the key to uniting different vampire clans. Since she's adopted by the Cullens, she might be seen as a symbol of a new way of vampire - human coexistence. This could lead to other vampires either trying to use her or trying to protect her from those who want to use her for their own gain.
There might be a fanfiction where the Cullens find baby Bella during a hunt. At first, they're not sure what to do with her, but then they feel a strange connection. As she grows, she starts to show signs of being a key figure in the vampire - human relations in their area. Maybe she has some sort of power that even the Cullens don't fully understand at first.
She might start by giving them the silent treatment. Just ignoring them completely when they try to talk to her, which would be a very human way of showing anger.
Well, it could be due to the way the Cullens interact with the other people in Forks. If Bella notices that they are being manipulative or using their powers in a way that she doesn't like to influence the townspeople, that could make her start to hate them. Also, if there is some kind of power struggle within the Cullen family that starts to affect Bella negatively, like she gets caught in the middle of it or she sees how it's causing harm to those she cares about, she might turn against them.
It could be that the fanfiction writer took a different approach to the story. In some fanfictions, the Cullens could be involved in situations that go against what Bella stands for. Perhaps they are written to be more secretive and untrustworthy, leading to Bella's hatred.
I'm not sure specifically as there could be many different takes on it. Generally, it might be about Bella using her singing in a context related to the Cullen family in a fan - created story.
Yes, it is quite common. Fanfiction writers often use this scenario to explore the relationship between Bella and the Cullens. It gives an opportunity to show the Cullens' caring side towards Bella.
