ger deny the extraordinary truth. Not only is he losing weight, he is also short
er than he was.

lows through its premise with remorseless logic, with Carey first attempting to
continue some kind of normal life and later having left human contact behind, ha
ving to survive in a world where insects and spiders are giant adversaries. And
even that is only a stage on his journey into the unknown.
