Hi, I haven't read your work yet and I will do when I find the time. But even when I've not read your work I want to tell you that I don't think you should worry about being labeled a copy cat and all that simply because, every books receives praise and criticisms, even the most famous books have been said to be copied from other books. So, as long as you know that you didn't copy, you don't need to worry about what other people thinks. And to be honest, authors do sometimes base their work on other peoples and take inspirations from other stories and that is perfectly fine.
Also, the Hunger Games and Divergent are all what are called dystopian novels, they are all based around the storyline of a bad ruler and people going to rebel against the ruler because they are unhappy about the way their city/country is ran. And so far I have not seen any similarities since your one is based on fantasies. Of course, I have not read your work yet and so I can't know for sure, but just so you know.
I read a lot, and therefore if you need any more opinions feel free to contact me at
[email protected], in the meanwhile I will find time to read your work!
good luck and keep writing.
