Revan: Star Wars Legends

Holy macaroni.
You can read this book even if you haven't played any of the KOTOR games. You just wouldn't know many of the characters (unless you've played SWTOR).
We're introduced to some of our KOTOR gang again and they embark on a new adventure to figure out what Revan is dreaming about.
The ending had my brain in shambles, and you have to read it to understand why.
