Thank you all for the feedbacks, and extra thanks for those who read all three chapters. The consensus is the content is too hard for younger readers and I agree. I do have some ideas to improve, and will work on them in the coming weeks.
Thanks, that is good advice. You totally get it that I am trying to paint a future scene, but somehow did not deliver. This is the first time I wrote any long story in my life. I tried on my own kids but that is too small sample size.
At very beginning I want to do it in comic style, kinda like “beast academy” style. But my art skill sucks, and ai image generator is not as good as I hoped. So I settled with chapter book, at least something I can produce. May be I should go game style "book" to be able to reach younger readers.
Thanks for the feedback. I have never done anything like this before so there are tons of mistakes. The flipping thing will generate a time sequence, I find it hard to explain myself.
