The Amber Room
Steve Berry
 The story is about judge Rachel Cutler and her husband Paul, a divorced American couple caught up in a treasure hunt for the long-missing Amber Room. A couple of competitive professional treasure hunters complicate matters. In their search through Germany to uncover the secrets behind its disappearance, they escape near-death in the tunnels running through the Harz Mountains, find themselves hanging off the edge of a tall church steeple, and discover a surprise in a hidden chamber of a Bohemian castle in the Czech Republic.
