I've been struggling a lot with trying to figure out if my book is Adult or Young Adult, because I can honestly see people as young as 16 reading it, but at the same time, I can see people as old as in their 50's and 60's reading it as well. The topics covered in it make this difficult for me. My main character is 17 at the start of the book and 18 by the end but the book revolves around him being forced into prostitution. Whenever I write about his job, it's only about the mental anguish it causes him, so it's clean in that regard. It contains profanity, however and I've seen people say that it's hard to get a YA novel published if it contains swearing inside. So, what exactly is Young Adult? Like is there a criteria for it? Does it have to focus on problems most teenagers face or can it be like my book? Thank you!
