Mysterium — Robert Charles Wilson

A TOWN ON THE EDGE OF TERROR...

In the early hours before dawn, a small Michigan town vanishes from the face of the earth. That morning the men and women of Two Rivers wake up in a world strangely different from their own--a world of curfews, food rationing, and secret police. Something has gone terribly wrong in Two Rivers, something that has to do with the mysterious government facility on the outskirts of town. For schoolteacher Dexter Graham, who has lost his family and has nothing left he values ... for twelve-year-old Clifford Stockton, driven by a child's curiosity and courage ... for Evelyn Woodward, torn between obedience to the state and loyalty to her friends ... and for physicist Howard Poole, haunted by the memory of his brilliant, enigmatic uncle, the only way to escape the nightmare is to journey deeper into fear.
