Frank M. Robinson. Waiting (1999) 303 pp.
Publishers description: There are people living among us who look just like normal human beings. Theyve been here for a long time—waiting. But they arent exactly like us at all. There are subtle physiological differences that might be found in a thorough medical and genetic exam. And that is something they really want to avoid. Theyll kill people to prevent it, in fact. Some of them can read minds and in subtle ways take over what you are thinking, and thereby for a while control you. They can make you love. They can make you die. One ordinary man in San Francisco, Arthur Banks, begins to find them out, and immediately his life and his family are in danger. Its a paranoidís worst nightmare. But thats just where it starts—Banks may well be fighting for the survival of the entire human race.
Setting: San Francisco
