Is the basic idea of my story any good?
Hello. I'm making this post to see if the idea for my book seems interesting or not. English is not my first language, so bear with me.
At first glance, the story might seem basic: a medieval fantasy world ruled by a Church, with a teenage protagonist who blindly believes in the system and their leaders, who joins an academy to become X (For the sake of naming, I'll call it "Warriors"), where she make new friends who broaden her horizons. The reader will see clear examples that the society, the system, has major flaws, and as one might expect from this type of story, they'll expect for the secondary characters and the protagonist to gradually discover them, ultimately fighting against the system they once wanted to join. But no: in my story, the protagonist ends up choosing the system over her friends, thinking that she's doing the correct thing, but basically sacrificing them; since 16 years of indoctrination don't just disappear in a couple of months.
The tragedy lies in the fact that, after finally becoming a Warrior, she only then realizes the flaws in the system, the horrific injustices, and, above all, the truth of her world. Ultimately, it's a story about guilt, about imposter syndrome, and about how one should never blindly follow any type of leader or system, especially if to them you are nothing more than another citizen.
There are, of course, more details to add, but I just wanted to know if the basic idea is any good or not!
