"I submitted a manuscript for a children's picture book to Children's Literary Agency last October and I only signed a 6 month contract. In the meantime, I have written another book with that series and am now working on a third book which is a chapter book for boys. My question is do you have any knowledge of Children's Literary Agency? I read on a website that they were a scam outfit under an umbrella of poorly managed services."
You haven't given them any money, have you? Children's Literary Agency is one of Writer Beware's Top 20 Worst Agents. Which you would have known if you'd heard of Writer Beware, or the wonderful people at Preditors & Editors (http://www.anotherealm.com/prededitors).
You, reading this blog. Go to Preditors & Editors right now and familiarize yourself with it!
When P&E or Writer Beware says that someone is a "Worst Agent" or "Strongly Not Recommended," what that means is that person is not an agent. He/she is committing a type of fraud that is very difficult for the law to prosecute. If you have paid this company any money, consider your legal options. You may be able to make business difficult for them.
But your money is gone.
