Someone with an experimental sniper rifle is after Chaingang, Chaingang is after everyone, more specifically Chaingang is after the Doctor... and you know what? I'm not even sure who the good guy is, the main character opposite Bunkowski. I got to page 186, and when I picked it back up my mind was wiped blank. The three before this were really good. We'll see about the 5th.
PS: This is a really HTF book and some kind soul on Facebook let me have a copy for like 20 bucks. Pretty nice.
