Marshall's Law by Ben Sanders is the 2nd book in the Marshall Grade series.
Ben Sanders’s 2nd book featuring Marshall Grade has all the elements of intrigue, action, and purpose found in his 1st book, American Blood. I listened to the audiobook and found it very easy to follow, and the wonderful actor, George Newbern, did an outstanding job with the narration. It was helped along by Sanders beginning each chapter with the character whose point of view was featured. I listen to audiobooks daily, so I know immediately if a narrator doesn’t hit the mark. George’s performance was spot on.
Though Marshall is a continuing character, there’s no need to read the American Blood to fully enjoy Marshall’s Law. However, I imagine you’ll go back and read it after meeting Marshall.
