When antibiotics ceased to work, Rory Stevigson lost her mother to an infection, the same type that has killed a seventh of the world's population. Then stoic and scarred Navy, a young military veteran, enters the quiet life Rory leads with her father on their farm, and Rory finds herself drawn to him despite his mysterious past . . . until he reveals the secrets her parents kept from her, including the fact that her own blood may hold the cure the world needs, and she is a target because of it.
The government’s research arm, TEAR, wants to sell the cure only to those who can afford it. The Resistance would give the cure away to all, and they’ve sent Navy to find her before TEAR can. Fleeing the dangerous government who would use her to gain power and struggling to survive a world turned upside down, Rory, her father, and their new protector narrowly avoid capture and death in their efforts to keep her hidden. Can she find the new path of human evolution before TEAR finds her?
