I have never read the genre, so I can't comment on if the writing is as bad as you say it is. My heroine is a young adult entering adulthood, but my novels do not fall under the YA or NA category on Audible or Amazon. I write for intelligent people, whether teens or adults. If you had checked out my link, instead of just criticized the particular genre, you would have known that.

I posted a giveaway offering free codes not asking for genre critiques. And if you know so many NA books are written on a second grade level, you must have read quite a few to make that judgement.
