When Hap Collins and Leonard Pine first see the bookmobile, it’s barreling down the middle of a country road, seconds before it smashes into their car. When they come to, they learn that the young boy driving the bus has died in the crash. Then they discover several bodies, hidden in the bookmobile’s rear compartment. Does one of them belong to the woman known as “Hoodoo Harry,” one-time mobile librarian, who’s been missing for the past several years? And are the child corpses the same kids who disappeared from the impoverished town where Hoodoo Harry lived? Armed only with the evidence contained in the now-destroyed bookmobile, Hap and Leonard set out to hunt the murderous culprit, risking their lives to make the children of Nesbit, Texas, safe to read once more.
