All her life Thalli thought she was an anomaly. Now she must use her gifts to fulfill the role she was called to play: Revolutionary. Back in the underground State against her will, Thalli is no longer the anomaly she was before. She has proven herself to be a powerful leader aboveground and returns with information that Dr. Loudin needs to complete his plan of uniting the world under one leader: himself. But he, too, has information. A secret he has kept from Thalli her entire life. A secret that, once revealed, changes everything about the person Thalli thought she was. Hoping to help Thalli rise up against the Scientists, both Berk and Alex join her underground, but their presence only brings more trouble for her. Now Dr. Loudin knows just the leverage to use on his captive, and she is forced to choose between the two of them. Is her first love her true love? Or does Alex ultimately claim her heart? Unsure of everything around her, including her own identity, Thalli doesn’t know where to turn. She knows she needs the Designer, but he seems further away than ever. What she does know, though, is that if she doesn’t do something to stop Loudin, the fragile world aboveground will be lost once and for all.
