Bram Stoker's Dracula. I've had it on the shelf for most of my life but for some reason, never picked it up. I was intrigued by the notion of "The Last Voyage of the Demeter" was based on a fractional part of a chapter of this book, so I decided to pick it up and read it. I was not expecting it to be as brilliant as it is. I understand a lot of classics are considered brilliant, but this book remains brilliant in how it's written and presented. It's just a joy to read.
