Hi.
Sorry for just popping here out of nowhere.
I have read your book His Only Treasure, and I want to give you an honest review so that you can improve your writing. I am not an expert, but I hope this will help you.
My first impression of this book is that it is impressive. It makes me want to read more and more. I must say that the plot is nice. The wording is good.
So, about the writing, please use the correct punctuation marks and end the dialogue with the correct ones.
For instance, Yoongi shouted, "I don't care if you don't come." (Like this, use a full stop or a coma if it's a statement. And don't give spaces before and after the quotes.)
You can read famous other books and see how they presented each scene and how they use punctuation. It will surely help you a lot. I have tried this before, and I improved a lot. Just get inspired. Don't plagiarise them, alright?
I was worse than you when I started to write. But, after trying and improving my writing skills, it got better. My books got good views every day, and I felt motivated.
For grammar, I recommend you use 'Grammarly.' It will help you a lot :)
I hope you don't take this negatively.
Have a nice day/night.
Cheers,
Ariel Unnie
