Fish, Fishier and Fishiest

So, I'm sending my children's book off to as many publishers as I can find. Most are saying up to six months for a response. Unless they don't respond at all if they're not interested in my manuscript. That's OK, I'm sure they have lots of submissions to go through. That means it's time to seriously think about my next book, I would like to have it written and the illustrations done by six months from now. I think that it's going to be about a fish this time.
