Dear Miss Snark, I got a problem. I have a novel. It's my first. It has a beginning, a middle, and an ending. BUT it is only 45,000 words. I am making some effort to make it longer. So here's the question. Is there ever a MINIMUM number of words for a first time novelist before sending query letters and shopping for an agent???
As a public service to my colleagues I'm going to tell you to not even think about querying an agent quite yet. If this email is any indication of your writing, you need to worry less about the number of words, and more about the quality.
If you want to find out more about word count, there are a lot of posts on this in the Snarkives. I'd recommend however that you spend more time in the Crapometer section.
