In 1986, the master of horror released the novel worthy of his title.  This novel reflected many of the themes, characters, and story beats that he had introduced in his earlier novels and stands as his ultimate thesis of the horror genre.  More importantly, it is the pinnacle of coming of age stories, a tale that places childhood friends at the center of a cosmic conflict, and only through the power of friendship can we overcome our fears.  If that doesn't speak to Mr. King's sensibilities, I don't know what does.  
Oh, and it has a scary clown!  
Ladies and gentlemen, I hope that you packed your bags, because we will be spending the next month in Derry, Maine, home of Pennywise The Dancing Clown.  Enjoy your stay, and keep away from the drains, the canal and the Barrens.  You'll never know what you might find there.  Or what might find you. . .
