Very good start to the series - glad I am reading Johnson's work after watching Season One on TV.  Great characters and vivid imagery, not to mention a sharp plot with several twists throughout.  Did not see the ending coming at all on this one which makes it even better.  Only thing that kept it from a full five stars was I found the writing a little choppy in some parts - but it is also the first novel in the series.  No doubt it will become more crisp with each passing installment.
