I picked this book up as a research tool for something I'm writing dealing with a theme similar to Frankenstein. I was very excited to begin reading it and finished it quickly. The book was very interesting. It did have a lot of good information. I would definitely recommend it. My only complaint is that I wish there was some more information on certain subjects. I also found the book rather depressing though I guess it can't be avoided. Mary Shelley and her circle of people all had very tragic lives.
