Cujo is admittedly pretty schlocky, but that doesn't mean it's not effective. The novel centres on two families, the Trentons and the Cambers. As the Cambers are preparing to leave town, their good-natured Saint Bernard Cujo contracts rabies and promptly turns murderous. It doesn't quite reach the supernatural heights or philosophical heft of some of King's later work, but Cujo's blunt, visceral prose still makes for an enjoyable narrative.
