Lyra — From a distance, the Haven Institute, tucked away on a private island off the coast of Florida, looks serene and even beautiful. But up close the locked doors, military guards, and biohazard suits tell a different story. In truth, it is a clandestine research facility where thousands of replicas, or human models, are born, raised, and observed. But when a surprise attack is launched on Haven, two of its young experimental subjects—Lyra, or 24, and the boy known only as 72—manage to escape. As they make their way through a new and menacing environment, they meet a stranger named Gemma, who has embarked on a perilous quest of her own. And as Lyra tries to understand Haven’s purpose, she uncovers earth-shattering secrets that will change the lives of both girls. Gemma — Gemma has been in and out of hospitals her whole life.
