So I heard from the first agent on Dissection. It was a rejection. It's okay, I'm used to rejection. And published authors get treated no different than unpublished authors. No feedback, and it was a form letter. The agent even forgot to change the book title in the body of the letter. So there's that.
I still have two more queries out there. Hopefully I hear from them soon. And I have a first round list of agents to send to, so I'll probably send a few out this afternoon.
