The first thing that comes to my mind is Naomi Novik's A Deadly Education. It's something like Harry Potter mixed with Lord of the Flies; imagine if Hogwarts had no teachers, and the building was self-aware, and it sometimes tried to kill students. The protagonist is definitely an introvert, and her narration is basically what made the story work for me. It's YA, but without too many tropes.
