Are there agents who are willing to represent 100-ish page women’s fiction manuscripts these days? And if so, what is the market? I see the petite novels in self-publish eBook formats but I am uncertain of the global mainstream market.
Generally agents are looking for books that publishers want to print. That means 80-100K words, not 25K. (100 pages =25K approximately)
I'm sure there's a market for shorter novels in ebook format where the writer/publisher can offer it for sale at a low price. Publishers have overhead that generally preclude offering books at that price unless it's a special, time-limited, discount.
