A TIME TO DIE by Nadine Brandes
How would you live if you knew the day you'd die?
Parvin Blackwater believes she has wasted her life. At only seventeen, she has one year left according to the Clock by her bedside. In a last-ditch effort to make a difference, she tries to rescue Radicals from the government’s crooked justice system.
But when the authorities find out about her illegal activity, they cast her through the Wall -- her people's death sentence. What she finds on the other side about the world, about eternity, and about herself changes Parvin forever and might just save her people. But her clock is running out.
