In Jonah's world, good and evil are no longer moral philosophies-they're science. From birth, humans are genetically altered and tested to separate them into two distinct groups: those who are morally flawless-known as perfects-and the others-darks-who are cast out from society and exiled to a subterranean world. Jonah Seckerd, a dark born with a mysterious gift, lives in the world below and struggles with his harsh existence. However, when he gets the chance to escape the fallen world he has lived in since birth, he emerges from the depths to discover a seemingly flawless society on the surface. Yet mysterious circumstances surround the utopia, and Jonah soon discovers that the perfection he sought might not be everything it seems. With the help of a perfect named Leah, he begins to unravel the society's web of intrigue and explore the haunting nature of his own past.
