Four thousand years ago, two hundred Watchers swore an oath on the summit of Mount Hermon.
In the present, an earthquake tears open a cave on the Golan escarpment, and epigrapher Dr. Leila Haddad finds a chamber her every instinct says cannot exist: archaic Aramaic carved into living rock, twelve iron stakes worn smooth in a ring, and a cold that listens back. That same morning her grandfather - a quiet Haifa antiques dealer who turns out to be the eleventh keeper of a two-thousand-year watch - is taken from his own shop. Four hundred kilometers south, intelligence analyst Tamar Reznik opens the envelope her grandfather left her in 1995 and learns that a small circle of patient men has spent decades moving armies with fear instead of truth - manufacturing a crisis built to gather the nations, in terror, at an appointed place and hour.
