Silver-Midnight, I completely understand about writing a novel sounding as a much harder task than writing a novella. I personally think the first 20k of a novel is easy - it just flows out - but it's the middle part that's terrible, like biting through a sour apple really. Plus, when a novella you sit down and say "okay, let's write 20k". With a novel, you sit down and say "okay, let's write 80k".
I'm also thinking of signing up for Camp NaNo. I've never done Camp NaNo before, but now might be the time.
I'm now at 20k words in my Ghostslayer MS. I think I'm good to go for another 1-2k, but then the first tough part comes.
