A Literary Agent

I need a literary agent. I'm working on a book about alcohol's role in Judaism, Christianity, and Islam. It was something I was working on before Katrina, but now that we're almost back in our house, I think I'll have time to return to writing starting this Fall. Earlier contracts for books I wrote, such as The Bible for Dummies, I think would have been better for me if I had a literary agent. So today I emailed some successful authors in biblical studies asking for advice.
