The Scorch Trials - James Dashner

Not flying through this one like I did with The Maze Runner, but that's partly due to business/laziness/Netflix (let's be real). I'm liking it, but I'M SO CONFUSED. I'm a little under halfway through and I still have no clue what's going on. Hoping I get some answers soon, because I think once I understand what's happening I'll like this even more and breeze through the rest.
