Hi all, I'm writing a mystery/thriller novel in the first person and my protagonist is a rebellious and cynical young woman with a dark sense of humour. She's a teenager in the prologue (14) and a twenty-something-year-old for the rest, and every time I write in her voice, I want to include swear words and bad language, because I feel like that's how she would think and talk. However, every time I go to write a swear word/slang, the writer in me tells me it's 'lazy writing' or could be offensive to readers, or that agents/publishers wouldn't be interested in a book peppered with bad language. Any advice? Target audience for the book is probably women in their twenties (20-29ish). Thanks!
