September Means Action!

For some weird reason the last few years I have read mostly action books in the fall.  I think it started way back with Catching Fire, then Mockingjay the next year.  There was I Am Number Four and The Power of Six.  Rot & Ruin came out in September and I read The Paladin Prophecy and Steelheart.  So, right now I want to read ACTION!  I just got The Infinite Sea for my library but I think I will be reading that first.  I also just read The Only Thing to Fear which was good and fulfilled some of my action craving.  I cannot wait for Firefight (and neither can some of the kids in my library).  What are some good action books you've read recently?
