Masada: Thou Shalt Not Kill
Avish, Shimon
When 18-year-old Daniel is abducted by Sicarii assassins and taken to their walled fortress of Masada, he's forced to let go of the Jewish Law he's learned from his parents and to adopt his kidnappers' code of violence and thievery, simply to stay alive.
Wracked with guilt but determined to survive, Daniel becomes part of the Sicarii culture, even marrying one of their soldier's sisters. Between violent raids against neighboring settlements to prevent starvation and being called upon to commit suicide along with all the other Sicarii residents rather than be enslaved by invading Roman forces, Daniel is faced with choice after choice that test his character, strength, and resolve and push him to discover the kind of man he wants to be.
