Clary's journey in the 'Shadowhunters' books is basically about someone who was lied to about their entire life finding out who they really are and what they can do. She starts off as this typical Brooklyn teenager who can draw, and then she's thrown into this hidden world of demons and angels. At first, she’s reacting to everything—her mom is taken, she learns her dad is a supervillain, she has powers she doesn’t understand. It’s a lot of frustration and feeling like a liability to the more trained Shadowhunters around her.
What I find compelling is how her development isn’t just about getting better at fighting, though she does that. It’s about her willfulness and stubbornness, traits that get her into trouble early on, becoming her greatest strengths. She never blindly accepts the Clave's archaic rules. Her growth is in learning to channel that impulsiveness into a kind of fierce moral leadership, often putting herself in danger to protect people the system ignores, like Downworlders and mundanes. By the later books, especially in 'City of Heavenly Fire', she’s not a bystander anymore; she’s making the hard calls and standing in the center of the conflict, weapon in hand, but her real power is still her heart and her refusal to give up on people.
She never loses that artistic core, either. That detail always felt important—her ability to create and see the world differently is what saves the day more than once.
