Hull Zero Three by Greg Bear A man awakens in a dark room to find a child pulling him to his feet and telling him to hurry. The room is freezing. There are bodies everywhere. He follows the girl who awakened him only to see her apparently killed my some sort of creature. He is alone, he does not know where he is or even what his name is. He only knows that he is a Teacher. So begins Hull Zero Three, the latest novel by Greg Bear. We and Teacher soon find out that he is on a starship, traveling slower than light and on a centuries-long voyage to another star system, and that something has gone very badly wrong. We also learn that “Teacher” is not unique. There have been other Teachers before him and all of them are dead. Will his fate be different. In many ways Hull Zero Three is about discovery and exploration. At the start, Teacher knows no more about what is going on than we the readers do. He even has trouble remembering basic words and concepts (like what those tiny points of light outside the ship are). He learns about the situation on the ship as we do. And the situation is complicated. It becomes apparently quite rapidly that the ship is damaged. Less rapidly we learn that a war has taken place, and perhaps is still underway. Teacher and the companions he finds along the way must both determine what happened
