Miles, the agent, replies to update to the proposal "Looks right ... will send to publisher today." Now, to quote the great Tom Petty, "The waiting is the hardest part..." The publisher has up to 60 days to reply with their right of first refusal. One thing that makes this different (harder? easier?) than the typical author submission is that I know that the right people will see this proposal. Between having a great agent and a great, proven co-author, it will get in the right hands. That is wonderful but has a downside. If it gets no interest, I won't have the excuse to tell myself that my work is great but just undiscovered. Maybe unappreciated, but not undiscovered. Weirdly makes me feel more exposed than if I were coming in cold as an aspiring first time author.
