I'm 50,000 words into my first book. Based on my plot and roadmap, that's about 25% of the way into it, so about 200k.
I have roughly 110 pages in a good place, as I've already re-drafted three or four times, polishing it up to get it ready for submission. This part is ready, but obviously the remaining 3/4 of the book isn't even drafted yet.
The question is: do I need to have a first draft completed to the ending in order to start talking to or submitting to publishers or agents? Is the first five chapters enough?
(Aside: I've done my research and I recognize that 200k is very long for a debut novel. But it's not unheard of, so I'm writing it first and I'll worry about word count later.)
