In one of my novels (it's a middle grade fantasy novel) the chapters average around 2,000 words. But the final climactic chapter is currently almost 7,000 words. I am considering splitting it into two because it feels unbalanced to have it as it is.
But I'm concerned that splitting it might break the momentum. On the other hand, not splitting it might make it seem to drag on relentlessly.
For further info, there is a natural break point, where the battle moves from one place (and one gear) to another - in fact thinking about it, it actually changes gear more than once, so could potentially be split twice.
Thanks for your input.
