My first ever book was 225k
Most o it , while I loved it, did not need to be there.
225k -- if your writing is tight (this will show in your UK sub/US query), and every scene needs to be there then you have a chance
If not, you don't
Sounds simple. But you perhaps (I did ) need some space from your MS, before you go back and look at every scene, every sentence.
Thta 225k mammoth I had? I cut that sucker to 110k
Sold it
Won a small award
Look at it. Really . Study it. STUDY OTHER BOOKS IN YOUR GENRE. Does this NEED to be here (no, a "scene explaining how X thing works" does not count, slide it into another scene! No, you do not need a page to describe the scene before you get to the action!)
I'll bet you can cut
Bet you a tenner
Yeah, I'm pretty sure this is why first time authors saying they have more than 120k words are pretty much shunned by agents and publishers - most have enormous amounts of cuts that they can make. Unfortunately for me, my manuscript is at 225k after beta readers, a professional critique from a best-selling author (who liked it enough to pass on to an agent), and a year of almost full time editing. It was originally at about 255k - there may well be a way to cut it further, but if there is, it's currently beyond my ability as a writer.
A good rule of thumb I was told is that every scene should be pushing the story forward in at least two ways, preferably three. A scene that's just world-building has no place in the story; a scene that's just there for character development has no place in the story; a scene that's just action for the sake of action has no place in the story. Every scene in your book shouldn't just be serving a purpose - it should be serving multiple purposes at once.
Having said that, not all published books (at least in the fantasy genre) are actually great examples of this. In fact, very few of them truly do it well, even the most popular ones - which is also why I think first-time authors often fall into those common traps. For example, I'd never cite GRRM as a good example of making every word matter. And I recently read The Lies Of Locke Lomora, another popular long-ish fantasy - and though I enjoyed it, I also found myself skipping literally pages of text (on a Kindle, admittedly) that really didn't need to be there.
So I guess what I'd add to your comment, Kissmequick, is that studying other books in your genre is a good idea, not only for how they do things right - but also to recognise and avoid what they do wrong!
