I really liked 'A New Understanding' in the world of Edward Cullen x Jacob Black fanfiction. This story delves deep into their personalities and how they interact. It starts with a tense situation between them but gradually builds towards a more harmonious co - existence, with some really interesting plot twists along the way.
I'm not sure about a specific title, but generally, these fanfictions often play with the idea of their contrasting personalities. Edward is the brooding vampire and Jacob is the passionate werewolf. A good fanfiction would likely explore how they might overcome their differences and find common ground. Maybe in a fanfic where they are forced to protect the same thing, like their tribe or the town, and in the process, their relationship evolves.
One popular plotline could be the two characters initially struggling with the unexpected pregnancy. Jacob, being pregnant, might face challenges within his pack as it goes against the norm. Edward, on the other hand, could be in a dilemma about how to protect Jacob and the unborn child from various threats in their supernatural world. There could also be a plotline where they have to hide the pregnancy from certain factions who might not be accepting of it.
Some werewolf packs that are more traditional might also act as antagonists. They might not accept Jacob's pregnancy as it goes against their beliefs and traditions. They could try to separate Jacob from Edward and force Jacob to deal with the pregnancy in a way that aligns with their pack's values, which could lead to conflict.
You can start by looking on Archive of Our Own (AO3). It has a vast collection of fanfictions, and you can easily search for Edward Cullen x Jacob Black ones. There are also some great works on Fanfiction.net, though the interface is a bit more dated.
There's a fanfiction called 'Shifting Loyalties'. In this one, Edward and Jacob are magically bound together in a way that makes them experience each other's emotions. This leads to a whole new level of understanding between them. They start to see the world from each other's perspective and it changes their relationship completely. It's unique because it doesn't rely on the typical love triangle scenario but rather creates a new bond between them.
One popular Jacob Black and Nessie Cullen fanfiction is 'The Unlikely Bond'. It delves into their unique relationship in a really interesting way, exploring how their different backgrounds in the Twilight universe come together. The characters are well - written and it has some really engaging plot twists.
A really good fanfiction could be set in the future, where Jacob and Renesmee are in a relationship. It could explore how their relationship is received by the different factions, like the werewolves and the vampires. There could be challenges they face, such as the werewolves not fully accepting Renesmee at first. But through their love and determination, they try to bridge the gap between the two groups.
Often, it depicts their relationship as a very special bond. Jacob is extremely protective of Renesmee, seeing her as someone he needs to keep safe. Renesmee, on the other hand, looks up to Jacob and trusts him completely.
One common theme is the struggle between different species. Since Jacob is a werewolf and Nessie is half - vampire, their relationship often has to deal with the prejudices and hostilities between their two groups. Another theme is love conquering all. Despite the odds, their love is usually depicted as strong enough to overcome any difficulties.
