An overnight camping trip! Not Harold's idea of fun. Too many mosquitoes, ticks and cockleburs. But when the Monroe family set out, their faithful dog Harold was with them, mostly because he remembered that camping could also bring s'mores and toasted marshmallows. Howie, the other family dog, and Chester the cat were also included in the trip. Only Chester thought the idea was completely insane. The woods, he informed Harold, were not only full of cockleburs and ticks, but of spirits, evil spirits who prey on the innocent. And on this, the worst night of the year—St. George's Eve, when all spirits are set loose—who knew what could happen. What Harold knew was that Chester was a well read, over-stimulated cat, full of weird ideas. He did not take Chester's worries too seriously. He had s'more to think about. But then, the Monroes set up camp near two strange men and their even stranger dog, and things began to happen that made even Harold wonder. Could Chester be right? This begins a long night, full of terrors and alarms, full of Chester's horrifying tale of how Bunnicula, the vampire bunny, was born and came to America, full of storms and a total sense of danger; and at the end came surprises that even Chester could not have predicted. Once again, the Monroe family may be the victims of evil forces or only of Chester's strange imagination. But whichever, the result is suspenseful and very, very funny.
