Monthly Recommendations is a Goodreads group that gives a montly topic to which people can recommend books. This month's topic is Monster Mash and I don't have a lot to recommend here, since I rarely read books that are scary or have a focus on supernatural creatures. I should read some Stephen King already but there are so many interesting books to read and so little time. Of course I've read fantasy books that have all sorts of monsters in them but I don't feel like I can recommend them for this topic. However, I do have a couple of things to recommend.
My first recommendation is The Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson. The book is not very scary but almost philosophical, reflecting on the good and bad sides of human nature. It is a very short book and a fast read, if you want to read a classic this is a good one.
My second and last recommendation is The Walking Dead comics by Robert Kirkman. I bet many people have watched the series but never read the comics, I didn't even know there was a comic until about a year ago. The series follows the comic book storyline but adds stuffs and mixes things every once in a while. The comic book is nothing like those superhero comics, it has lot of dialogue and at points very graphic pictures of zombies and dying people etc. If you want horror, with this you can find it.
