I rarely give five stars to books of this type, but this one has superbly intricate plotting and character development. He also brings in some issues about PTSD for veterans of the Iraq War, without shoving it in your face or letting it take over the story. Well done. Call it 4.5 stars. This is the third in a series, but there's no need to have read the first two. I haven't read the second one, and this one worked fine for me all on its own.
