I first read this book thinking it was "just another story where people scream and fill the screen with blood," but after I had finished it, I realised how amazing our silly childish nightmares can be if translated into such a tale of horror, humanity, fate and justice. Mary Shelley wrote this book when she was just 19, I think, but after finishing it, I couldn't but wonder how brilliant she was. The only thing I regret is that she didn't write more books as taking as that one. I recommend everyone above 13 to read this book, and you'll surely enjoy it as much as I did. If you missed that book, you missed half of the "Horror" definition.
This is one of the few nightmarish books that have not much "story stuff," but can leave you quite puzzled and startled once you've finished them, trying to understand what is what, and why did who.. etc
But to me, I've never read such a book. Just the first few lines, and I couldn't help finishing the book the same night. The thing that really got me mad was the thoughts of the main character, Gregor.
It's a real nightmare I wish I never go through, especially how it ends. Really as weird as it is loathsome.
Read it at your own peril...
