So, I read the first chapter and here are my thought so far.
First, you TELL a lot more than you SHOW. On a book, you should try to have the ratio between the two leaning more on show. Unless there's a moment that demands a lot more of you explaining things, like a lore explanation, for instance.
The pacing also felt too fast. Too much happens in a single chapter in very little "time". It doesn't let the reader breath in before you jump between moments.
You do manage to create a sense of intrigue with Teo being different. Altough it didn't hook me that much, I think that with some refinements to the prose and pacing you'll do just fine.
If you could, I would appreciate if you could review my own story. I also would love some serious critiques so I can improve. Anyway, have a wonderful day and I hope you keep going with your story.
