I've started a separate Fragments and Feedback area for novels only.So if you want feedback on a novel, please start your topic there.
You may post the first 13 lines and/or a short summary of the novel (what you'd put in a query letter).
You may ask for feedback on the first 13 lines and/or on the short summary, and you may ask if anyone would be willing to have you email them a partial (the first 20 pages and an outline/synopsis of the rest) for critiquing.
If someone wants to critique the whole novel after having given you feedback on the partial, that's fine. You can arrange to email it to them if you like.
But, please, do not email someone more than the partial otherwise.
