Written by Carole Stivers, The Mother Code is set in 2049, when scientists are rushing to save humans from a bioweapon that spun out of control. Their last hope is to raise genetically engineered children in special machines programmed with the Mother Code, which ensures that each child will grow up unique. In the Southwest, Kai was raised by a robotic mother, Rho-Z. When the government decides to shut down all Mothers, Kai must decide whether to part from Rho-Z or to fight for the only mother he knows.
