Do I need an agent?
I think Stephen King said it best, you’ll know when you need an agent. That being said, it’s hard in some genres to submit without one. It can be done, but you’ll have a harder time. The only thing I can really say is that agents are like spouses. You’re a team and it’s important that both of you understand and share your vision for your career.
If you’re having trouble, then fire the agent. I always say that it’s better to have no agent than a bad one. But in the end, it’s up to you. The one thing I would suggest is that you review the http://pred-ed.com/ website before you sign on with any agency.
