Emmett Atwater isn’t just leaving Detroit; he’s leaving Earth. Why the Babel Corporation recruited is a mystery, but the number of zeroes on their contract has him boarding their lightship and hoping to return to Earth with enough money to take care of his family. Before long, Emmett discovers that he is one of ten recruits, all of whom have troubled pasts and are a long way from home. And Emmett will face the ultimate choice: win the fortune at any cost, or find a way to fight that won’t forever compromise what it means to be human.
