I knew not to query during the holidays. Now, I wonder if agents will be barraged with queries during the first couple weeks of January, and it's better to wait a little longer(present blog host excluded of course).
I've mentioned I'm not reading queries during the holidays in a couple of recent posts. A lot of my colleagues are actually taking query hiatuses (they're deleting anything that comes in during the hiatus so they don't stare at a Stack O'Doom come Monday.)
But I really want to encourage you to NOT get in the habit of thinking there is a good or bad time to query. Short of an actual hiatus with the queries getting deleted, your query goes in the mailbox and gets read. You have zero control over when that reading happens. The only thing you can control is getting it in to the mailbox.
Send your query when it's ready to go. If you're trying to avoid the holiday deluge, everyone else is too, and Monday 1/4/10 is probably going to be the slowest day for queries since 12/25/09.
And know this: tonight I was shepherding the incoming queries into their little query corral when I saw one with a subject line that ignited my interest. Damn right I read it. And called the author that MINUTE to request a full. Had a very nice conversation with him, and I plan to read his project tomorrow.
Would every agent respond that way? No. This project is a long standing passionate interest of mine. You don't know if your book is in that category with an agent and you're better off to take action (send the query) than try to suss out the "perfect time" to do so. The perfect time is right now.
