I read all but the three newest ones. I'm in the middle of Command Authority. I just can't find the time to read anymore. I even read SSN and his little game franchise books that bear his name but are written by other people.
I thought they were all excellent with the exception of the franchise books and SSN.
Whether or not he got every little detail right or not doesn't matter to me. He's a hell of a storyteller and his books will forever be my favorite.
