On an April day in 1937, the sky opens and fire rains down upon the small Spanish town of Guernica.

In the run up to World War II, a sleepy Basque village is savagely bombed by the Nazis in an unprovoked war atrocity that still shocks today. Picasso immortalized it. Sibi lived it.

A serial killer on the loose. A profiler with a hidden past. A world at war.

Trust is a luxury no one can afford.

This pulse-pounding, brilliantly twisting new thriller from New York Times bestselling author Karen Robards is a gripping tale that will leave you questioning everything.
