Written in 1764, and widely regarded as the first gothic genre novel. It’s a very quick, strange & gloomy story with an equally menacing castle as the backdrop. 
It’s hard to critique it without acknowledging it’s been the inspiration for nearly all gothic novels since. So, at times it feels cliche but in context to when it was written, it was actually full of fresh ideas. 
Overall, I liked this book. It maintained a tense, dark & haunting tone throughout. The characters were easy to sympathise with each battling their own demons. 
Not an essential classics read unless you’re a big fan of gothic stories.
