One common theme is self - discovery. Female potters often start out not fully aware of their powers or potential, and the story is about them finding out who they really are. For example, they might learn about their family history that has been hidden from them and realize their true place in the wizarding world.
Perhaps there's a plot against Harry by some dark forces, and the Potters believe that only they can protect him properly. They might think that the people who have been taking care of Harry so far are not equipped to handle the new and more dangerous threats. Also, it could be that the afterlife in the wizarding world has some rules or opportunities that allow them to try and get Harry back into their family fold. They could have been given a second chance, so to speak, and are eager to take it.
A theme that is often explored is the idea of legacy. The Potter family has a great legacy, and Ginny's interaction with them can bring out how she fits into that magical world's history and future. Also, love and romance can be a part of it, as relationships might develop between Ginny and some of the Potter family members or their friends.
There's also 'The Female Potter and the Lost Artifact'. In this fanfiction, the female Potter is on a quest to find a powerful and long - lost magical artifact. Along the way, she has to face many challenges and make new friends in the magical world. It's really exciting as it combines elements of adventure, magic, and friendship.
In this fanfiction, apart from Voldemort, there could be some dark wizards who are working independently but have the same goal of seeing the Potters dead. They might be jealous of the Potters' popularity or have some old grudges. These dark wizards could be in league with Voldemort or acting on their own, and they would be a big obstacle for Hermione as she tries to save the Potters.
Well, it could be that Hermione uses her time - turning device to go back in time and warn the Potters about Voldemort's plan. Maybe she disguises herself and manages to get into their hiding place, then uses her magic skills to set up powerful protective spells around them that Voldemort can't break through.
One possible motive could be that the Potters discovered some dark plot by the Malfoys involving Harry. Maybe they found out that the Malfoys were planning to indoctrinate Harry into their pure - blood supremacist ideology against his will. So, to protect Harry from that, they kidnapped him.
