I'm working on a mystery novel for kids and having a really hard time targeting it. I know my style is not terribly gritty and I've done some mystery puzzle activities for students that seem to be popular among 7th/8th graders. So I was thinking of targeting MG and have thoughts about a book written around a school. I've read plenty of advice suggesting mysteries for MGs shouldn't be about murder, but when I read other MG books, certainly kids detectives are sometimes kidnapped and implicitly threatened with death, jewel thieves, kidnappers, gangsters, pickpockets, do appear in these books. Kids even beat up bad guys occasionally. So any advice on targeting a particular audience, or maybe the inverse, figuring out what audience your writing is good for?
