To follow God's word and prevent another Tribulation, they must preserve absolute normality among the surviving humans, plants, and animals-and therefore practice a brutal for of eugenics. Humans with even minor mutations are considered blasphemies and either killed or sterilized and banished to the Fringes, a lawless and untamed area rife with animal and plant mutations. But there may be hope for this dark civilation in the form of a new set of human mutations...A classic science fiction novel by the author of The Day of the Triffids and The Midwich Cuckoos.
