Noa Torsen is on the run. After outsmarting the sinister corporation behind Project Persephone, Noa and her friend Zeke move stealthily across the country, rescuing runaways who are targeted to become test subjects. Noa knows all too well what happens on the Project's operating tables: She still bears the scars. And she's determined to keep the Project from using other teens as guinea pigs. Back in Boston, Peter anxiously follows Noa's movements from his computer, using his hacker skills to feed her the information she needs to stay alive. But he's desperate to do something more to help. Especially when he learns what Project Persephone has done to his ex-girlfriend, Amanda. Then, in an explosive confrontation, Noa and her team are trapped in the one place they thought was safe. It will take everything Noa and Peter have to bring down the Project before it gets them first. And with no one to trust and enemies hiding at every turn, they may be the only people alive who can.
