Gemma and Lyra's parallel stories come to an end in Oliver’s thrilling sequel to Replica (2016). Having escaped from the Haven Institute, Lyra and Caelum are living in a Tennessee trailer park with Lyra’s father. They're having trouble adjusting to life with humans and when Caelum leaves without warning, Lyra follows him to Philadelphia in the hopes of finding a cure for the illness that is slowly consuming her mind. Meanwhile, Gemma just wants a normal life with her boyfriend Pete, but her powerful father has other plans for the replicas—unless she and Pete can stop him. But they aren’t safe either and when they're mistaken for the escaped replicas, Gemma and Pete are captured and taken to the Haven Institute.
