Hey i wanted to say that i started reading your book, walking, and it's really good. Keep up with your good work.
A friendly advise I'll give you is to explain the emotions of the characters when they're saying something, explaining how they sound or look like. In my opinion this makes the reader get more into the characters and the story. Of course i am not forcing you to change the way your story is written or how you'll write them in future i am just giving you a friendly advise that you don't have to take, but you can use to improve in the future. We all have talent and we should appreciate that, even though there are people that are better than us, we should take that as and inspiration and a challenge to make our work better.
I want to thank you again and i hope we could get along
