Genetic modification is Reya's living nightmare. "Sequencing," as they call it, was used to cure every disease passed on through genes. Alzheimer's, cancer, you name it, gone. Sequencing left the world with a race of genetically impeccable people, called the Perfect. They are given every luxury, a truth all too real for sixteen year old Reya. She's lived her life under the system of segregation, longing to see the other side of the river, where people can be more than store clerks. Someone will destroy the world as she knows it, and it just might be Reya herself.
