Michelle, is a "no" from one of you at your agency a "no" from all? I know agencies differ on this. Thanks.
(I would imagine the two of you share info., but just checking)
I do thank you for your great information here.
If a manuscript has been rejected, then a no is a no - we do share info about those and if something is good and just not for one of us, we always check the other person before declining.
If your query has been rejected, then chances are the other agent hasn't seen nor heard of it, so go ahead. :)
