Professor Gargoyle, The Slither Sisters, and Teacher's Pest are all awesome horror stories by Charles Gilman. Professor Gargoyle is about a boy that sneaks up on his teacher one night. He realizes that his teacher is actually an evil gargoyle demon. The Slither Sisters is also about a boy whose classmates actually turn out to be gorgons and try to destroy the school. In Teacher's Pest, bugs are crawling all over the boy's school. Read it to see if a giant fruit fly actually destroyed the world or not. I liked these books because of their freaky horror moments. I would recommend these books to kids who love horror stories.
