Brooklyn Harper’s worst nightmare has become her reality. She has been captured by Isolation… Trapped in a white-walled labyrinth by Juneau Malloy, Brooklyn is faced with the horrors of Isolation’s finest training yet. The skills she learned as an Omen Operative in Camp Number Eleven are put to the test in the form of brutal assessments of her strength, skills, and fortitude. Confused and disheartened, Brooklyn and the group of renegade Omens prepare for whatever trials Isolation has in store for them. Juneau has caged her once again, but Brooklyn is far from broken… When Brooklyn finds out her best friend Gabriel is alive, she goes on a violent rampage in search of her, but instead earns herself a stint in solitary confinement. Juneau attempts to tame Brooklyn through grueling exercises before offering her one radical choice. Brooklyn must hand over her freedom in order to spare her friends. She’ll become a showpiece Juneau will auction off to the highest bidder for her skills in assassination, defense, and combat. There must be a way out, and the renegade Omens have to find it… Brooklyn has no intention of becoming Juneau’s latest achievement. During a mind-warping training simulation, Brooklyn uncovers Isolation’s greatest secret and their darkest mistake. Juneau Malloy has created something far more sinister than the Omens, and it’s ready to eat the world alive. As the battle with Isolation intensifies, Brooklyn is faced with her most dangerous choice yet… Save her friends—or save humanity.
