No, I haven't even begun to give up on getting an agent for Assassin's Nightmare. The manuscript continues to circulate. I have two fulls out right now and an offer to look at it for a second time from a third party if I made revisions. Those revisions are made, and I'm preparing to send it back to the agent who suggested them.
And today I got a new request for the partial. According to one agent's blog, editors are looking for thrillers with dark and damaged heroines. Well, mine is something of a science fiction thriller. My heroine is definitely dark and damaged. Maybe a window of opportunity is opening.
