Masters at Arms (Rescue Me, #1) - Kallypso Masters What a great prequel! There's a little bit of sex, but not a ton, but for being a prequel, this was quite lengthy and chock full of great information. I loved seeing where all the guys came from and what pushed them into the military -- well, I guess we only saw why two of them went. We also get a good clue of their demons, and we get to see how they met and what they bonded over. I think this is going to be a great series if this prequel is any indication.
