This book was a fitting beginning to my October reading, as it's a classic horror novel. Compared to modern horror, which is often very gory, this book was more of an existential horror piece. It's definitely wonderfully creepy, in tone and in content, and left me with a sense of dread. Recommended.
I'm going to claim this book for the "yellow" category in the Color-Coded Reading Challenge, based on its cover, as shown below.
