Enslaved by their genetics.
Oppressed by their creators.
Fighting for their humanity.
Kayla is a GEN—a genetically engineered nonhuman—in a world torn apart by castes separating GENs from “real” humans. In the wake of a devastating bomb blast, Kayla has been brought to the headquarters of the organization that planted the bomb, and many others like it, in GEN food warehouses and homes. Her biological mother tells her that Devak is dead and that Kayla must join their terrorist group, which is ramping up for something big. Now Kayla must pretend to embrace this new role in an underground compound full of paranoia as she plots a way to escape and save her friends.
Meanwhile, Devak has emerged from his healing in a gen-tank, only to be told that Kayla is dead and his family has fallen from grace. Can he overcome his grief enough to notice the clues that point to Kayla?
As Kayla and Devak fight to find each other and stop the bloodshed, the Tankborn trilogy rushes to a thrilling conclusion!
