Please Miss, Can I have another?
I have an agent. Unfortunately, I'm not pleased with him. He doesn't communicate. He won't show me my rejection letters and ignores my emails. I'm going to stick out the year with him because my book has already been sent to 8 houses (no idea how many if any have rejected yet), so no one else would pick me up for that book anyway. There's the backstory, here's the question. In the meantime, I have finished another novel, one in a different genre from the one he's representing. Can I shop this new novel around to agents while I already have another novel contracted with a different agent? Can you have two agents at one time (for two different novels)? I really don't want to give him this new novel, too, because we don't agree on communication expectations. But I don't want to end it with him yet because he's in the middle of submitting my old novel.
You don't have an agent.
You have someone holding your book hostage.
Trust me on this: there's a difference.
You usually have one agent at a time for books. The exceptions are if you are writing in two very different categories: children's picture books and porn; academic non fiction and chick lit. You get the idea.
The trick there is the agents all know about each other.
What you can NOT do is start shopping a book behind this guy's back no matter how odious he is. One at a time. Like yanno...wives.
