Some of my earlier posts referred to the number of words in a query letter. I recently spoke with a friend, who is is a NYT best selling author. (14 novels) He had an interesting comment. "Any agent who adheres to an absolute number of words, is someone you do not want to represent you. If your query is 325 words--so what? If it's a great letter--no one will be counting words." What does everyone think?
I think your friend may be a highly successful writer, but he certainly doesn't know all the agents and editors out there. Some of the very best absolutely want you to adhere to a strict word count.
And why not? If you can't do this basic thing, if you can't keep something as simply as a query letter to 250 words, why should an agent or editor believe you can do anything else right?
If an agent or editor says "One Page Only", or
No more than 250 words", there isn't a reason in the world to send more than one page or 250 words, other than an inability to say what you want to say using one page or 250 words. This is a bad sign.
If it's a great query letter, you never, ever need more than one page or 250 words.
A great query letter often sells the book with a single sentence, and sure doesn't need anywhere near 360 words, so why take the chance?
