There are monsters outside the city walls.



Harvard is small, anxious, and plagued by a constant tremor, which is not an ideal combination for a desert scavenger. He and his crew are under constant threat of desertwalker attacks, and Harvard is nearly useless against them.



When the biggest mistake of Harvard's life separates him from his crew, he must learn the secrets of the desert beasts in order to survive the dangers of the dusts. Returning to Bastion with a surprising ally, Harvard is forced to choose between saving his crew or allying with the 'monsters' who rescued him.



Harvard never saw himself as a hero, but when the beasts of the dusts implore him to aid their rescue mission, he holds the lives of crabs and humans alike in his trembling hands.
