Pike Logan and Jennifer Cahill travel to Poland, hired to verify artifacts hidden for decades in a fabled Nazi gold train, only to find themselves caught amid growing tensions between East and West. A Russian incursion into Belarus under the facade of self-defense is trumped by a horrific attack against the United States, driving NATO to mobilize even as it tries to determine who is behind the strike. On the brink of war, Pike and Jennifer discover that there is a separate agenda in play, one determined to force a showdown between NATO and Russia.
