Book suggestions

I am currently planning out a novel to write that I will eventually publish when it is completely written and edited. I have an idea of my story but I would love some opinions or recommendations that could help me.

Could some of you give me things:
- you would love to see in a novel
- you would hate to see in a novel
- any themes you love
- any love interests etc.

I encourage a discussion that could help me on may journey!
Thank you
