Monument 14: Savage Drift (Monument 14 Series Book 3)

In Monument 14: Savage Drift, the stunningly fierce conclusion to the Monument 14 trilogy, author Emmy Laybourne ups the stakes even higher for a group of kids who have continually survived the unthinkable. Can they do so one last time?
It's over.
Dean, Alex, and the other survivors of the Monument 14 have escaped the disaster zone and made it to the safety of a Canadian refugee camp. Some of the kids have been reunited with their families, and everyone is making tentative plans for the future. And then, Niko learns that his lost love, Josie, has survived!

Or is it? For Josie, separated from the group and presumed dead, life has gone from bad to worse. Trapped in a terrible prison camp with other exposed O's and traumatized by her experiences, she has given up all hope of rescue. Meanwhile, scared by the government's unusual interest in her pregnancy, Astrid--along with her two protectors, Dean and Jake--joins Niko on his desperate quest to be reunited with Josie.
