Well, you could have a plot where Artemis has to compete in an academic decathlon against a rival school. But there's a mystery behind the other school's team, like they're being controlled by a fairy in disguise. This would bring in the elements of the original 'Artemis Fowl' series while still being set in high school.
One idea could be Artemis starting a secret club at high school to study ancient languages and artifacts, leading to unexpected adventures. Maybe he discovers a hidden code in a school text that links to a mythical treasure.
Another plot idea is to focus on her relationship with Artemis during a difficult time, like when he first starts getting involved in more dangerous activities. She might be trying to protect him while also respecting his growing independence. It could show the internal struggle she has as a mother.
One idea could be exploring the family's past adventures that haven't been told in the original books. Maybe there was a secret mission that Artemis's father went on when he was younger that now has consequences for the family. Another idea is to focus on the relationship between Artemis and his mother, showing how she deals with Artemis's extraordinary intelligence and his often dangerous exploits. Or perhaps a fanfic could center around a family reunion where long - lost relatives show up and bring new challenges and revelations to the Fowl family.
Another interesting plot could be a time - travel adventure. Maybe something goes wrong in a fairy experiment and Artemis and Holly are sent back in time. They have to figure out how to get back while also not changing history too much. For example, they might accidentally prevent an important event in fairy history and have to fix it before they can return to their own time. This would involve a lot of exploring the past, interacting with historical figures in both the human and fairy worlds, and using their combined skills to solve the mystery of how to get back.
One plot idea could be that Artemis and Holly are on a mission together and during a dangerous moment, they share a kiss out of a sudden rush of emotion. Another could be a story where they have to pretend to be a couple for an undercover operation and gradually develop real feelings, leading to a kiss. Or perhaps a plot where Holly is injured and Artemis kisses her to bring her back to consciousness in a moment of desperation.
One idea could be that Artemis and Holly have to team up to solve a mystery in the fairy world that's affecting the human world too. Maybe a powerful magical artifact has been stolen and they need to find it before it's used for evil.
Another fanfic could focus on their relationship development. Maybe they start off as rivals in a competition of wits at a prestigious academy. As they face various challenges together, they gradually realize their respect for each other turns into something more, like friendship or even a budding romance.
One interesting plot could be exploring his dad's early adventures in the criminal underworld before Artemis was born. Maybe he was on a secret mission to retrieve a powerful magical artifact that was lost for centuries.
One idea could be that Percy is a new student at a high school where Artemis is the star athlete. Percy has his own mysterious powers that he tries to hide, but Artemis senses something different about him. They start off as rivals in a school competition but gradually learn to respect and work with each other.
Another concept might be alternative timelines. Like what if Artemis made different choices at certain crucial points in the story? It could lead to very different relationships with the fairy characters and new adventures.
One idea could be that Artemis and Minerva are on a joint mission to recover a powerful magical artifact. During their adventure, they start to develop deeper feelings for each other. Maybe they get trapped in a dangerous place and have to rely on each other for survival, which intensifies their connection.
