Thank you, LizB, for suggesting I post on querytracker.net! It took a few days before I got around to it. I'm nervous about putting out a piece of work for criticism. When I sent out my first couple of query letters, I felt sick to my stomach every day I didn't get a reply. I irrationally kept expecting replies like, "Who are you, and why are you sending this to me?" But really, that's part of the point of writing - just putting everything out and taking criticism.
I've got some GREAT suggestions so far - suggestions that address a lot of problems I have with my current query. Once we're in Nashville and I finish polishing this draft, I'll feel a lot more comfortable about sending out queries again.
This is a weekend of goodbyes and packing.
