A Time to Die

Three hundred sixty-four days, seven hours, and sixteen—no, fifteen—seconds left to live. Like everyone else on the east side of the Wall, Parvin Blackwater has a clock counting down the days until her death. At only seventeen, she has only one year left.
When the authorities find out she has been illegally sharing a clock with her twin brother, she is cast through the Wall—her people's death sentence. What she finds on the other side about the world, about God, and about herself changes Parvin forever and might just save her people. If she can get the word to them before her time runs out.
