Yes, it's worth reading.
It's about two mice and two little people. They all live in a maze and hunt for cheese (which is a metaphor for happiness).
They all find a big supply of cheese at Cheese Station C. The amough of cheese gradually decreases but the little people doesn't notice. When the cheese one day is gone the mice move on. But the little people stay and try to figure out where the cheese has gone.
One of the little people, Hem, doesn't wan't to face the change or adapt and is angry that someone has moved his cheese and is waiting day after day for the cheese to come back. The other, Haw, realizes that the cheese is gone and is not comming back so he decides to go back into the maze in the hunt for cheese.
Cheese could be family, love, comfort of home a job with an airline etc.
Anyway I'm going back to the maze!
