My agent experience is somewhat limited, but I’d add that it’s not the end of the world if you don’t get one.
Although I worked with an agent for two/three years, when she decided not to work with me any further (bearing in mind that nothing was signed between us in all that time) it gave me the freedom to strike out on my own. Course, I appreciate that’s not ideal for everyone, and having an agent and a publishing deal is still a Really Good Thing for those who want to proceed that way. It just didn’t work out for me, personally.
Are you trying any indie pubs or small presses direct, PB?
