A prison ship that's left abandoned so they prisoners have to get by in whatever way works for them with the very minimal of assistance from the outside world. Some of the groups go all the way to psycho cults, others are in it for their own pleasure and then there's Dred's group that's trying to survive with murderers under some control. Jael from the [book:Grimspace|1828067] books is here but it's about 30 years later. I hope in some future date we find out what happened to that group. Here it's pretty much gritty, horrible struggle after gritty, horrible struggle. Very good book.
