During the time of King Chizkiyahu, Sancheriv, the wicked King of Ashur, threatened to surround the city of Yerusalayim. It seemed that many other cities had already fallen to Sancheriv, but the Prophet, Yishayahu, told the people to trust in Hashem. The danger was: the powerful enemy could easily win by simply blocking off the water supply of the Jews. Our story follows a fictional character, 11-year-old Yonatan, and his desire to help protect his family and his people. The historical details of daily life and dramatic threat of the siege combine to create a suspenseful page-turner for children.
