I would like to give you feedback but I couldn't switch my point of view to 7-14 years old. As far as I read your concept, It's amazing. You're using the story to deliver a (key) message(s) which is something that slowly fades away in modern media. It makes your novel valuable.
Why choosing one where you can enjoy both? If you're a fan of tea and wanted to try something similar, I suggest you try drip coffee. The beans are light to medium roasted, less bitterness, more acidity and aroma.
I'll try to make one for you if I finish a chapter tonight.
Edit: If you don't mind, could you summarize Cadmar appearance and personality? He's the MC, right?
