It's always very nice... and reassuring to have a second opinion. Finding an agent is a very funny business. Well, you have to laugh to keep your spirits up and maintain a healthy perspective on life.
Today, my YA novel, The Reaping, was rejected for the second time by the same literary agency, but by a different agent within, both of them very nice and polite. Not my mistake! I hadn't chanced my arm and tried two agents in the firm, hoping they wouldn't talk to each other. It was their mistake. Overloaded with submissions, mine clearly surfaced twice like a drowning man before he sinks altogether.
I submitted the synopsis on 17 November 2014. It was first rejected five months later in March 2015. Over a year later - today, 22 December 2015 - it was rejected again.
I pointed out the error in a cheerful email, which was received with equal good heart. No one has been hurt, just a little time wasted.
What have I learned? Submitting has a funny side. Agents eventually read everything, sometimes twice!
