So i'm a big fan of manga's like Beserk, Gantz and books like GOT, Prince of Thorns and i am attempting to write my own grim dark fantasy (First Book) tackling very controversial subjects such as death, violence, religion, sexuality, human nature and such. My question is, how do i know if iv'e gone too far too early and is there such thing as too much? I don't want to chase off my readers with a graphic scene before they get to the juicy parts or understand whats going on but at the same time i don't want unicorns and rainbows for the first few chapters as i draw my readers in. I enjoy action, violence and a story which tackles philosophical or cultural issues, something to make me think and question the status quo whilst keeping me entertained but i know that some people are really put off my anything too deep, any advice for setting up this world with a good stance? Thanks!
