I really like the fanfic 'Percy and Hestia: A New Bond'. It starts with Percy seeking solace at Hestia's hearth and from there, a unique connection forms. It's filled with tender moments between them and shows how Hestia can be a source of stability in Percy's chaotic life. The descriptions of their interactions are very vivid.
One key theme is often protection. Percy is usually portrayed as someone who wants to protect Hestia, and she in turn protects him in more of a spiritual or emotional way. For example, in many fanfictions, Percy will stand up to threats against Hestia's domain.
There's also 'Hestia's Protege'. In this fanfic, Percy becomes an unofficial protege of Hestia. It has some really interesting plot twists. For example, Percy learns some ancient secrets from Hestia that help him in his battles against the new threats emerging in the world of the gods.
One way their romance could be portrayed in fanfiction is through Percy seeking solace in Hestia's hearth. Hestia, being the goddess of the hearth, represents warmth and home. Percy, having gone through so many harrowing adventures, might find a sense of peace with her. They could share quiet moments by the fire, with Hestia listening to Percy's tales of his quests. Their relationship could be a slow - burn one, starting from Percy's initial respect for her domain and growing into a deep, unspoken affection as he realizes how much her presence means to him in a chaotic world of gods and monsters.
In Percy Jackson fanfiction, a relationship between Percy and Hestia could be really interesting. Hestia is the goddess of the hearth, representing home and warmth. A love story might involve Percy finding a new kind of peace and comfort in Hestia's presence. Maybe after all his adventures, he discovers a different kind of love with her, one that's more about stability and a sense of belonging.
Perhaps a story where Percy is chosen by the Fates to mediate between Hestia and Artemis. There has been some sort of misunderstanding between the two goddesses. Percy, with his charm and unique perspective, tries to get them to see eye to eye. He arranges meetings in different places - sometimes in Hestia's warm and cozy domain, and other times in Artemis's wild and untamed forests. Through Percy's efforts, they not only resolve their differences but also realize that they can work together for the greater good.
In a Percy Jackson and Hestia lemon fanfiction, it could be that Hestia uses her powers related to the hearth to create a lemon - like glow around Percy. This glow gives him an extra boost of energy during a battle. They form an unlikely bond, with Hestia seeing Percy as a symbol of hope for the future of the demigod world. And the lemon aspect could be metaphorical, like a fresh start or a new hope that Percy brings, much like the refreshing feeling of a lemon.
Hestia's possessiveness can shape the plot in many ways. It might lead to Percy being isolated from other characters who could be important to his development. This in turn can create a series of events where Percy has to either break free or come to terms with Hestia's possessive nature. Also, it could attract the attention of other powerful beings who either oppose or support Hestia's possessiveness, adding more twists to the plot.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). There are often tags related to 'Percy Jackson' and 'Hestia' which can help you narrow down the search. Another option is Fanfiction.net, though the tagging system might not be as detailed as AO3.
One possible fanfiction could be about Percy Jackson seeking the guidance of Hestia, the goddess of the hearth, who has now become a champion in some way. Maybe she is a champion against a new threat to the demigod world. Percy could learn new skills or gain unique powers from her. For example, powers related to home and family, which could be used to protect Camp Half - Blood in a different way than before.
