Outside a peaceful town in central Maine, a monster is waiting… Cujo is a huge Saint Bernard dog, the best friend Brett Camber has ever had. One day Cujo chases a rabbit into a bolt-hole, a cave inhabited by some very sick bats. What happens to Cujo, how he becomes a horrifying vortex inexorably drawing in all the people around him, makes for one of the most heart-stopping novels Stephen King has written.
