Dear Miss Snark:
I am in the final stages of writing a historical novel. The editing is almost over. It has been great fun. In a couple of weeks the unfun part will be starting, with queries and the like. One problem: I hit the word count function on my word processor and I have 235,000 words! And this is after a liberal use of pruning shears.
Is it going to be an immediate turnoff for an agent or publisher? The thing is divided into four parts of 55,000/60,000 words each, but it is a single story.
Miss Snark is as fond of lifting weights as the next slacker couch potato but 235,000 words is 135,000 too many.
Yes, something this size is a problem. First, if you're a new author, you're going to be most likely published in paperback (tpo or mm). 235,000 words makes a HUGE book, and subsequently the price is high. When you are starting out you want the lowest price you can do because while Miss Snark lies on the couch she reads econ texts that tell her price and demand are related.
Right now you are in love with your words, and the idea of pruning them is anathema. Get over this at once. You must be ruthless with your prose. Trim it like kudzu.
You have a couple choices.
First is prune. There's a LOT of advice about this in the comments trails on previous posts about length.
Second, just split the thing into two, or better yet, three books.
Three, query and see what you get.
I vote for #1 with all four feet.
