While the book does introduce other adversaries like the LEP (Lower Elements Police) and the fairies who are suspicious of Artemis, the conflict between Holly and Artemis is the core driving force of the story.
Here's why:
* Opposing sides: Holly is a LEP officer tasked with protecting the fairy world, while Artemis is a criminal mastermind who wants to exploit it for his own gain.
* Intellectual clash: Both are brilliant and resourceful, making their encounters a battle of wits.
* Personal animosity: They start off antagonistic, but their interactions eventually develop a begrudging respect, even a hint of something more complex.
While Holly might face opposition from other fairies, their conflict is often a consequence of Artemis's actions.
