Ah the query letter. Bane of my existence. Okay, actually I think the synopsis is the bane of my existence, but the query is a close second. There was a brief post about the importance of writing a good query on Janet Reid's website here in which she talks about how sometimes that query can stay with you for a long, long time- even becoming part of your back cover copy.
So how do you know when you have a strong query? Of course there are countless resources on the web for how to write a query, but how do you know for sure- 100%- that you've got it down? I think the obvious answer is that you know you've got it down when agents actually request material. But at what rate? Is a couple of requests out of 20, or 30... or 50 enough, or is that just the ratio of agents willing to overlook a so-so query if the idea is good?
And the next question is when do you decide to revise your query? It's hard to know if a lack of response means you have a crappy idea or just a poor query.
What do you think? Does anyone have personal experience to share?
