Once upon a time not so long ago a monster came to the small town of Castle Rock Maine He was not a werewolf vampire ghoul or unnameable creature from the enchanted forest or snow wastes; he was only a cop Cujo is a huge Saint Bernard dog the best friend Brett Camber has ever had Then one day Cujo chases a rabbit into a bolt-hole Except it isn't a rabbit warren any more It is a cave inhabited by rabid bats And Cujo falls sick Very sick & the gentle giant who once protected the family becomes a vortex of horror inexorably drawing in all the people around him
