Cujo

Though now dated due to technological advancements, Cujo is still a riveting story. I could only imagine reading this before the days of cell phones. King is able to take an event that could happen to anyone (though much more plausible in the time period that it was written) and make it into a nightmare. Take a good dog with rabies, mix in some car troubles, a dash of broken home(s), and you have a deeply dark story that is as hard to put down.
