After finishing a 91k word crime novel I was so excited that I couldn’t wait to hit “send.” And of course the first five queries were quickly rejected, as were the second batch of five, and the third and fourth. After licking my rejection wounds, I evaluated my ms and query, read a couple of great books about the “first pages hook” thing, and "starting your book in the right place." I revised the ms accordingly, polished it, revised the query and hit “send’ on another batch of five. I was elated to get two requests for partials and one for the entire ms! Hey, maybe I was getting somewhere with my dream!
One of the partial requests was from a big name agent with years of churning out ‘Big” books. The response was a rejection with detailed feedback and praise, but no request to R&R. The full is still out there with another partial.
My question is: should I resubmit to the Big Name agent after revising? Or am I wasting his time, and mine? And why would someone as busy as this man give such a detailed revision request just to reject it?
Generally speaking, you don't requery for the same manuscript unless asked to do so by the agent.
On the other hand, what's the worst that could happen if you do? Well, ok, you could get eaten by sharks, consigned to Carkoon, subtweeted by Agent SnootyPants. Last I looked none of those were actually fatal. Not even metaphorically fatal.
And what you need to succeed in this business is to be bold. In fact, it's one of the Rules for Writers.
So, here's what you'll do. You make sure that revised manuscript is polished till it gleams. No typos. No missing words (that's a big one). No homonyms. The standard for revised mss is even higher than requested-only-once mss.
Then you query Agent Big Name and say "your advice on revising the manuscript was invaluable, and I followed it. May I send you the revised version for consideration?"
You might hear no. You might hear nothing. No harm, no foul.
But you might hear yes.
Trying and failing is better than not trying at all.
And remember, agents are on the hunt for good work. If you've got it, I want to see it.
