The dovekeepers

Four women, Yael--whose father, an expert assassin, has never forgiven her for her mother's death during childbirth--Revka--a local baker's wife who witnessed the murder or her daughter by Roman soldiers--Aziza--a warrior's daughter who was raised like a son--and Shirah--a woman born with uncanny insight and knowledge of ancient magic--are drawn to Masada, a mountain in the Judean desert where, in 70 CE, nine hundred Jews withheld for months against armies of Romans.
