Most of us don't look forward to writing the query, but in my opinion, it's the most important part in snagging an agent or editor's attention.
This is really hitting me because I'm a judge in a contest that includes the query as part of the submission.
Several queries were not good. Not horrible, but not anything that would entice me to read more. Imagine my surprise when some of the entries were really, really good. Solid writing, intriguing plots...yet I would've never guessed by the query.
If an agent doesn't read pages, they have nothing to go by but the query.
And if the query doesn't dazzle: form rejection.
What do you know about writing queries? Have you written yours and was it easier than you thought, or more difficult?
