From the New York Times bestselling author of Before I Fall and the Delirium Trilogy, come two astonishing stories in one epic, masterful novel that explores the issues of individuality, identity, and humanity. Turn Replica one way and read Lyra`s story; turn the book over and upside down and read Gemma`s story! Lyra`s story begins in the Haven Institute, a building tucked away on a private island off the coast of Florida that from a distance looks serene and even beautiful. But up close the locked doors, military guards, and biohazard suits tell a different story. In truth, Haven is a clandestine research facility where thousands of replicas, or human models, are born, raised, and observed. When a surprise attack is launched on Haven, two of its young experimental subjects - Lyra, aka number 24, and the boy known only as 72 – manage to escape. Gemma has been in and out of hospitals for as long as she can remember. A lonely teen, her life is circumscribed by home, school, and her best friend, April. But after she is nearly abducted by a stranger claiming to know her, Gemma starts to investigate her family`s past and discovers her father`s mysterious connection to the secretive Haven Institute. Hungry for answers, she travels to Florida, only to stumble upon two replicas and a completely new set of questions.While the stories of Lyra and Gemma mirror each other, each contains breathtaking revelations critically important to the other story. Replica is an ambitious, thought-provoking masterwork.
