Meanwhile, we are introduced to the other characters who figure prominently in the post-holocaust world. The Henry family appears, their friendship with Randy providing a model for the cooperation that will be necessary between blacks and whites in the wake of the disaster. Lib McGovern is Randy's a love interest. Lib's father's persistent refusal to believe that war is imminent can be read as a stinging critique of complacency among the American public. And finally, we meet Dan Gunn, Randy's best friend, who fills an important role after the disaster as a selfless, courageous doctor. With the arrival of Helen and her children, all the major characters are in Fort Repose.
