I just wrote the intro chapter to my first full-length novel. It's going to be a longer, more involved adventure of the Misevelin Salvage team, with a lot more characters and stuff going on. This is something I've been waiting to start on for a while, because I wanted to spend a little time working on short stories and novella-length works before diving into a full novel.
However, what I want to talk about in this post is how difficult it can be to write in a medium-hard or hard sci-fi system. I've already set up that there is no artificial gravity, and that most ships don't bother to install a rotating part, since most space flights are relatively short (due to Shelf space travel--FTL, basically).
