From New York Times bestselling author John Scalzi, The Human Division is released for the first time in trade paperback with a new introduction by the author. The people of Earth now know that the human Colonial Union has kept them ignorant of the dangerous universe around them. For generations the CU had defended humanity against hostile aliens, deliberately keeping Earth an ignorant backwater and a source of military recruits. Now the CU's secrets are known to all. Other alien races have come on the scene and formed a new alliance--an alliance against the Colonial Union. And they've invited the people of Earth to join them.
