Nobody knows who the Watchers are. But they are around us. They observe us. They see things we can't see . . .
David Moore lives in the city. Six months ago, his father disappeared. Now David has seen him again . . . in an abandoned subway station, surrounded by a mysterious crowd of ghostlike people.
No one else sees this. No one else can.
Is David's father dead? Or is he . . . elsewhere? In order to find out, David More must enter the world of the Watchers.
