Parable of the Talents by Octavia Butler

Lauren Olamina's love is divided among her young daughter, her community, and the revelation that led Lauren to found a new faith that teaches "God Is Change". But in the wake of environmental and economic chaos, the U.S. government turns a blind eye to violent bigots who consider the mere existence of a black female leader a threat. And soon Lauren must either sacrifice her child and her followers -- or forsake the religion that can transform human destiny.
