Dear Miss Snark,
Just sent in my query to EvilEditor and he brought to my attention that there is such a thing as ' too short a book'. My own is just about 40,000 words for a non-fiction piece. Will this be a big problem when soliciting an agent? Having already tried to add more - for there is are a lot of events I can add - it seems to subtract from the texts value. Any advice on which is better of the two evils?
Mr. Evil is right (of course). 40,000 words is about half a book (stand down all you sharpies ready to point out exceptions-this is GENERALLY not specifically speaking).
The reason I'd elevate a plucked eyebrow at 40K is that I'd wonder if your narrative was fully developed and your story well told. I'm a minimalist to the core, but cursory is not minimalism.
The other part of the equation is 40,000 words means you're going to have a lot of white space on the page or a 48 point font to use enough pages for a book. It's bad enough paying $27 for a hardcover of 400 pages, but $25 for a hardcover with 100? yuckola.
It's not a deal breaker but I'd be put off by the low word count if your query landed on my desk.
