Long-time writers are chuckling/grimacing/nodding. I think we've all gotten The Email, probably more than once. Of course, my critique partner is over the moon. He thinks he's about to get an agent, who will, no doubt, sell his book very soon. Who knows, maybe all that will happen. I've heard tales of writers who DO get agents and DO sell their books. I really hope it happens for him. Good luck, buddy!
But... The first time I got The Email I was super-duper-excited. I dropped everything and revised, revised, revised, according to the agent's suggestions and sent it off with bated breath. I never heard anything back, despite eventual repeated attempts at contact on my part.
Over the years, this has happened a few times. I've even gotten The Call. This is the same thing but in verbal form. Again, after I sent off my revisions, I never heard back.
Somehow, I always do the revisions. And sometimes these revisions even result in a stronger book. I always seem to have a least a little trickle of excitement that I can't tamp down. Maybe writers are eternal optimists?
So, you will never guess what just happened... I got an email from an agent that says, "I love your book! I'd like to represent it, but before we sign a contract, please revise the entire thing and send it back to me." (!)
Wish me luck!
Good luck to you as well with The Email. :)
