Since entering the Safe Lands, Mason has focused on two things: finding a way to free his village from captivity and finding a cure for the disease that ravages many within the walls of the Safe Lands. After immune-suppressive drugs go missing in the clinic, Mason discovers his coworker, Ciddah, may know more about the Safe Lands than imagined…and may have an agenda of her own. At the same time, Mason s brother Levi is focused on a way to free the remaining Glenrock captives, while Mason s younger brother, Omar, decides to take the rebellion against the Safe Lands into his own hands as a vigilante.

Soon all three brothers are being watched closely—and when Mason stumbles onto a shocking secret about the Safe Lands meds, his investigation just might get those closest to him liberated.
