There is violence in the world around us. I wish there was less (well, after I polish off my hit list of course.) You, the savvy writer, need to know the difference between essential and gratuitous violence.
Being able to talk about violence and the aftermath is essential to healing. Silence equals death, a phrase coined at the start of the AIDS epidemic, still applies. Shaming victims requires they be made afraid to speak. Writing stories helps end that silence.
Two books very close to my heart involve acts of
unspeakable cruelty and shame. They are central to the story; they in
fact ARE the story. How those acts are presented in the story leaves no
room for misunderstanding; they are not there to show how terrible a
villain is; they are there to show how flawed the protagonist is.
And they are certainly not there for titillation.
The reader is not shocked; the reader is not horrified. The reader is heart-broken.
How you write about violence will make a huge difference in how far I'm willing to read in your novel. It's not what you write , it's how you write it.
