I've written two stories around 60k each, and at first I wasn't very confident that they would be enjoyed. As a result of this fear, I chose to self publish. However, one of my fans is an English teacher and she tells me both books are quite enjoyable. With this in mind I feel I'm doing something right, so I'm considering looking for an agent. Because of this, I have two questions: 1. Would it be worth submitting something to an agent which I have already self published, or should I hold on until I have written something new? 2. Please may you recommend an agent if you know a good one? I understand there are a wide range of agents, some busier than others and some with better links to bigger publishers than others. My preferred genre is science fiction with a target audience of ages 12 and up.
