Received a response that wasn't a rejection

It's amazing! I finally got a response from a publisher that wasn't a resounding "no". All the agents I queried have rejected me at this point. I'm down seven. I figure nineteen more and I'm in the Dr. Seuss category. It wasn't an "I want your book" but it was an "I'm keen to read the rest of your manuscript." I'm completely thrilled with that. Even if this editor doesn't end up wanting it, it's at least a positive step.
