The Whisperer in Darkness by H. P. Lovecraft
What a wonderful surprise to find this classic in the list. I have read a number of authors who sight Lovecraft as one of their sources of inspiration and even some who have built upon the mythology he developed. I had not ever read any of his works. He is famous for his influence on the horror genre of the 20th century and numerous songs and games have been influenced by his work, unfortunately, he did not experience financial success during his lifetime. This is written in a first-person narrative with a bare minimum of dialogue. It also has a far more challenging vocabulary than is usually found in YA or even modern fiction with only a little archaic vocabulary. It was a scary page-turner edge of the seat, classic horror novel. I’ll never look on the hinterlands of Vermont the same.
