[Koby]

So my book is about 3 kids/monsters/demons who find an academy for demons. Some humans have wandered into this academy and those who do are killed. The main character's friends instantly find their demon like abilities while the main character doesnt. Gettimg closer to the end, most of the demons/monsters want to kill the main character because they think he is a human. Around the end he finds out that he is a monster/demon after all. He is half demon half angel and his father is the headmaster of the academy. If you have any info on the book please let me know.
