Talking of structure, but has anyone else noticed how many authors use repetition to bulk out their novels? I've recently read Terry Pratchett, Jim Butcher (Dresden Files) and Joseph Delaney (Spook's Apprentice), and they all have repetition in passages. With Butcher & Delaney, writing in the 1st person, often where their main characters are mulling stuff over and over, going over what they've learnt already and deciding what to do next. Pratchett just seems to like to write things in different ways and keeps the all the little darlings in, rather then choosing just the one line or paragraph of prose. I guess in Pratchett's case means that one line of carefully crafted prose doesn't stand out in the scene.
Anyway, just something to file away in my #whatIdiscoveredtoday file, to be brought out when I'm struggling to get up to 80K and I'll think, aha, I'll just repeat a few things.
