When  the bodies of the dead come back and attack people, the fighting in the Civil War stops. What doesn't stop is the racism that was inherent in the United States. Now, 20 years after the shamblers first appeared, black children are taken and trained for combat duty.The system replicates the hierarchy of slavery.  "Better" girls are trained in elite schools to be bodyguards to wealthy white women. They guard them from shamblers and serve as chaperones as the white ladies socialize.  Other girls end up working in the fields clearing shamblers as they approach towns.  Those people don't have a long life span.For me the story got most interesting when Jane and some companions are sent west to a planned community run by a pastor and his son, the sheriff.  Everything is set up for the safety and protection of white families but it is all run on the forced labor of black people.  The white overseers are so terrified of their black charges that they deliberately undermine their ability to fight shamblers by not giving them adequate weapons thus weakening the defenses of the whole town.  They won't listen to the advice and expertise of black women until it is literally life or death.This book didn't interest me as a zombie/horror story.  It was at its best when showing off the absurdities of racism.  From phrenology to tell who is white and who is black to medical experimentation on unwilling black people to unequal distribution of assets this book highlights many aspects of systemic racism by placing them in a fantasy setting where people should be more interested in working together for survival than upholding an arbitrary hierarchy.This review was originally posted on Based On A True Story
