People will reject your book project.
I hope most people will like it.
However, 100% of the people will not vote for, accept, and love your book.
It just isn't possible unless your a dictator, then 100% of the people will have to vote for you.
However, when writing your book, remember that some people will not like it.
My advice: write it anyway.
Check out this list of sci-fi and fantasy novels that publishers rejected.
The world wouldn't be the same today had these not been created.
Imagine the other awesome books (and movie ideas) that didn't get completed, published, filmed and shared with the world because someone rejected it.
Please, Create your work and share it with the world.
