Surrounded by Extinction, the Keep is enclosed within a fifty foot wall. Only desert and destruction exist beyond. Inside this lone fortress, the Council of Constraint controls everything: curfew, clothes, career, names... In return for surrendering  freedom, citizens receive survival. Most don't  mind the exchange. The Son of Sara isn't like most people. However, no one seems to share his growing sense of dread. His mother is too busy. His father is dead. His friends think he’s reckless. Only  nightly visits beyond the wall offer any relief. Then one day, he receives a letter signed by the Nightingale, the Keep's mysterious dissident. After that, nothing is the same. Unless he learns to live by the rules, Sarason could be called before the Council. He should stop before he is caught, but first he wants to know the Nightingale's identity, and why he was chosen to help her cause.
