Inch by inch, day by day, Scott Carey is getting smaller. Once an unremarkable husband and father, Scott finds himself shrinking with no end in sight. His wife and family turn into unreachable giants, the family cat becomes a predatory menace, and Scott must struggle to survive in a world that seems to be growing ever larger and more perilous, until he faces the ultimate limits of fear and existence.

This is the terrifying novel that inspired the classic Hugo Award-winning motion picture, also written by Richard Matheson.
