The 173 (Travis Bishop #4)

When a former colleague comes to the ranch asking Travis to put aside his easier life, to save CIA agents, he must quickly decide if that is something he has no choice in.
From cover to cover, there is no letup in the action with many surprises built in.
Even a country under siege in real life that others are including in their novels helps to make this thriller stand as opposed to taking anything away from it.
