To save Abby and stop the Hellions for good, Claire must find the machine her parents built before the attacks, and fix it before the monsters return. To do so, she needs the help of her crew, and must ignore the secrets and rivalries between her captain and the man she saved.
Because the Hellions are not the only dangers following Claire. Twisted humans and old enemies surface to stop her and destroy all she loves. While she is determined to endure the trials, a single betrayal could shatter the hope of a better world, and force Claire to make a choice that will cost her dearly...
