Full Black is the next installment in the Scot Harvath series by Brad Thor. I have read all of them so far. They are pretty much all the same, not literature but quick, enjoyable reads.
He has gotten worse at his characters having their own voices. There are many different people who all sound the same to the point that when they have conversations with each other it sounds awkward. He is also getting further into this dogmatic right-wing mentality that parts of this book just sounded really preachy.
I will keep reading them because they are silly, but I wouldn't start with this if you haven't read the previous nine.
