It has been almost three years since Thorn disappeared. Encouraged by revelations from Farouk's Book, our feisty heroine Orphelia decides to act-and continue to challenge authority in her quest for truth and freedom. Under a false identity, she travels to the ark of Babel, a joyful, modern and cosmopolitan territory. Hidden in the heart of Babel is an elusive secret, the key to the past and to an uncertain future. Will Ophelia's talents as a reader be enough to avoid the traps of her increasingly formidable enemies? Does she have the slightest chance of finding Thorn again?
