Quite a good story, needs some proofreading and re-writing though
Quite a good book! You do have a good chapter length (a thing some people (like me) struggle with) in each chapter, and an intriguing plot. You also have a nice pacing going on, keep that in mind when you re-read your message.
Read the story now
However, if I may add a small point of critique: You seem to use a lot of so-called text walls. By which I mean, A lot of text without any spacing between it. I saw that you use a lot of dialogue, don't be afraid to split those text-walls into smaller pieces, using dialogue as your guide.
You also had a question about something missing about your story... What I suggest is the following: without looking back at your story, write down the goal you had in mind (what emotions did you want your reader to have when they finished the book?) . Then, with the mind of an outsider , re-read your book and write down key plot-points. Then compare the emotions you felt with your goal. Do they match? Great, then you have a good storyline and can add things (like extra challenges your characters has to go through, or deepening of your characters' psyche). Otherwise, try to pinpoint the fault and rework it.
Hope this helps, good luck!
