If you're a writer with no track record who is fortunate enough to get an agent with a top reputation to represent a novel, how long should you give that agent to make the sale before concluding another agent might be better?
That's like asking, "how long is a piece of rope?" The answer varies with each agent, and having open communication lines between agent and author is vital.
That's not always the case, Tri: some new agents have great contacts, knowledge and experience. For example, if they've worked as editors and have moved to the other side; or if they've worked as an agent's assistant, and have been promoted. They'll be keen to build their list, and will be very approachable and have great promise.
I know of someone who was promoted from assistant to agent in the last couple of weeks, who is actively building a list, and works at one of the best agencies there is. He's been there some time, and has been very well trained. He's going to go far, and anyone who gets him as their agent is going to be very well looked after.
I do see a lot of promotions and shuffling in PM, and those agents definitely have experience. Many have editorial backgrounds and some have served internships.
My problems with agents in the past have stemmed from the brand new ones who suddenly appeared out of nowhere--gleaming mission statements and all but no real experience and no sales to date.
I had four agent offers on the last book and three of them fit that bill.
First, my agent has never told me she's top-notch, but other people have, and she reps a huge name in the genre she works, so I take those as good signs. Having said that, the owner of the agency accepted my novel and gave it to her, and I've never felt she was as enthusiastic about it as he was. Over the three years, she has submitted my novel to the top U.S. publishers in the genre, and that has eaten up time. She also told me Hurricane Sandy last year delayed things. When I email her with a question, she replies, but she rarely contacts me first.
I have six completed novels ready for submission, including two in her genre. I've tried to send her the second one to read, but she insists we must focus on selling the current one first. She's also told me, by the way, that it's fine if I seek other representation for the novels outside her genre, which I'm doing.
Remember, agents don't sell books. The books sell themselves. (Or don't)
What a good agent does is get the ms to the right place at the right time. A good agent knows which particular editors might like a particular ms. A good agent also will have a good rep -- editors will read what she sends, because they know from experience and reputation that anything the agent sends to them will be worth looking at.
But the book still has to stand on its own. An editor may pass because books with similar styles and/or themes have not been selling well lately.
It simply may not grab the editor, who may think it's quite good, but just not for her.
In most cases, blaming an agent for a book not being picked up, esp right away, is assigning blame where there is none.
Now, if none of the editors submitted to haven't even bothered to respond, that may be a different thing, and reflect on the agent's ability to present the book.
My own agent forwards every response that she receives, good bad or indifferent, whether it's weeks, months, or even longer, and gets responses from all the editors she's dealt with and 90% of the others.
The last response from an editor was basically, "I love this book, but unfortunately I just don't think it will sell."
A new agent isn't going to change that opinion.
