Finding such a specific fanfiction can be a bit of a challenge. Some fanfiction communities on platforms like Tumblr might also be a good place to ask. There could be fans who have come across this type of story and can recommend it. Another option is to check out some Harry Potter fanfiction forums. People there are often very helpful in sharing their favorite reads.
One possible plot development could be that Harry tries to find a way to escape the marriage. She might use her magical skills and the help of her friends to break free from Voldemort's control. Another could be that she pretends to go along with the marriage while secretly planning to undermine Voldemort from within.
There are indeed such fanfictions. Some explore really interesting concepts within this odd scenario. For example, in some stories, the forced marriage is a part of a dark plot by Voldemort to gain more power over the wizarding world through Harry. Others might focus on how Harry copes with this situation and tries to find a way out while also dealing with his complex feelings towards Voldemort. It's a very unique concept that can lead to some very creative storytelling.
Yes, there are some fanfictions with this rather strange premise. You can often find them on various fanfiction websites like Archive of Our Own (AO3). Just search for the relevant tags.
One plotline could be that Voldemort wants to use the marriage to gain control over Harry's special powers. Another could be that it's part of a prophecy that neither of them can avoid. Or maybe it's a political move in the wizarding world to end the war between the two sides.
One possible plotline could be Harry trying to find a way to break the forced marriage bond while secretly gathering allies to fight Voldemort.
The relationship may develop through a series of challenges. For example, they might face opposition from both the Death Eaters and the Order of the Phoenix. This external pressure forces them to rely on each other more. Fem Harry uses her intelligence and courage to help Voldemort face his inner demons, and Voldemort uses his power to protect Fem Harry from those who want to harm her. Through these shared experiences, their relationship deepens and evolves into a loving marriage.
One way this plot could develop is through a political or family power play. In the wizarding world, marriages are sometimes used to strengthen alliances. Maybe the Malfoy family and some powerful wizarding families or political forces force the situation. Harry, being female in this fanfic, might initially resist but then gradually find some unexpected common ground with Draco as she gets to know him better in this forced situation.
She would probably be furious at first. Harry is known for her strong will, and being forced into a marriage, especially with Draco, would go against everything she believes in. She might try to fight it directly, using her magic skills to break free from whatever is forcing this marriage.
One popular 'Voldemort adopts Fem Harry' fanfiction is 'The Dark Lord's Daughter'. It has an interesting take on how Voldemort's character would change with a daughter figure. Another one could be 'A Different Path for Fem Harry' which explores the magical world from a new perspective with this unique relationship.
I've heard of 'Harry and the Female Voldemort: A New Alliance'. In this fanfic, they are forced to work together due to some magical circumstances. It has great descriptions of the magical world and how their relationship evolves from mutual distrust to something more complex.
