So, I'm kinda kicking myself right now...
Seeing as I wasn't able to access the "Submissions" page, I didn't see this little diddy:
"Always let us know if you are making multiple queries to other agents."
I queried Sara and got a rejection -- very blunt...5 words.
Not to be deterred, I sent off a query to Andrea Somberg, with roughly the same content sent to Sara (of course, it was individualized.
). I followed the instructions on the "Agents" page, but as I said before, I didn't see the little instruction on the "Submissions" page. And I have queried other agents and had some requests for material (not the full manuscript -- just the first ten pages, which were requested by another agent who does not reply to queries if not interested).
Oops.
I hope this doesn't come back to bite me in the rear.
