I am new to writing and have paged down many months on your blog. I'm not sure if you answer this type of question, but I will ask.
I am at the final chapters of a YA. My question to you is my ms to much for a YA? In brief it takes place in a high school and includes relationships, drugs, sex, kidnapping/torture and murder. It has description to feel the emotions, but not to much depth in the sex and drug portions.
Really, anything goes in YA these days. Basically, don't write smut that has no plot, or PWP as we say in fanfic. (Porn Without Plot or Porn Without Point) And don't be excruciatingly descriptive unless you're being raped and it's an autobiography. Then sit back and wait for the awards to roll in.
Also, do you ever give pro's/con's on query letters?
If by this you mean review them, no.
