I'm sitting on two unedited, but basically complete manuscripts right now. One is a sci-fi novel and the other is a children's story. Since they're both wildly different in theme and subject matter, how would I go about submitting them to publishers? Do I submit one, (let's say the sci-fi novel), then if it gets picked up, mention the kid's book? Do I submit them both to different publishers? Can I be published by two different publishers at the same time? Do I submit them both to a publisher that publishes both Sci-fi and kid's books? Do I just submit the kid's book to publishers of kids books? Or should I just try to get an agent and let them deal with it? I have no idea what to do.
