Dear Miss Snark,
I am an unpublished member of Mystery Writers of America.
I used their Mentor Program to review the first fifty pages of my first novel and the review was good to outstanding.
I also submitted the first two chapters to a writing contest and got back three reviews/critiques. Again the reviews were good to outstanding.
Is this something that I could include in my query letter to an agent? I can understand perhaps one good review but when three or four people give you the same positive comments, I think that it is perhaps something to add in a query letter.
What do you think?
Comments from readers do not belong in a query letter. Not even if they are superbly marvelous agents who participate in the MWA mentor program. And REALLY not if they are judges in a writing contest.
If your writing is as good as they say it will stand on its own. As they say "don't tell me you have a good novel, SHOW me".
