I am Kapsar, an interesting read
I’ve covered about halfway through your book and I must say that it’s a unique yet sad read. (Sad stories are also just my thing as well) Kaspar is such a pure sweetheart at first, who doesn't adore him? And knowing how he is innocent through your descriptions of his thoughts makes me feel great sympathy for him when he’s subjected to unreasonable abuses and unfairness by those “dominant.” I think his insanity has every right to surface and show the others the monster they’ve raised in him.

I love the way how Kaspar’s right mind transfers to the other darker side of himself. Your pace with the transition is wonderful. Though, in my opinion, perhaps you can add more physical descriptions and make them balance with the thoughts of the character, as well as adding more information about each scene to prevent confusion. If you intend to keep certain info for better plot twists later on, I completely understand.
That aside, your narrative is well written, the metaphors intriguing. And there aren’t many mistakes at all! Great job and keep it up. I hope you’d achieve what you wish in writing! (I'm not a professional writer myself, so all of the above are only purely my honest ideas!)
