Seventeen-year-old Katherine Dennard will risk the freedom she fought so hard to gain to rescue the man she loves, even if it means making an unthinkable deal with Saul, a high-ranking military officer determined to capture her and destroy all Natural-Born rebels. But the arrangement may forever strip her of the quiet life she desires with Micah and her newborn son and thrust her back into the dangerous world of The Institute — where only perfect, genetically-modified babies are allowed to survive. Natural-Born rebel, Micah Pennington, will die in prison before he gives up information that would put Kate and her child in danger or reveal the secrets of the Hidden City. And if by some miracle he does escape, he must find a way to obliterate The Institute and their genetic engineering practices once and for all. Saul Goodman fosters trust with the rebels in order to infiltrate their society, reveal intel, and devise a way to eliminate them. Kate holds the key to the downfall of The Institute, and Saul will use her baby against her, stopping at nothing to protect The Institute’s future. Will Kate choose to save Micah even if it means placing the life of her baby in Saul’s hands?
