This week's topic is favourite / least favourite supernatural being
Alright so technically I have two favourites: vampires and the fey. So I guess I am cheating and choosing both of them!
I still like mythology and the gods / goddesses / deities / demi-gods, etc, often featured in books (i.e Percy Jackson, though I haven't actually read it...just an example) but they aren't anywhere close to my favourite supernatural beings. I prefer fairy-tale retellings to greek mythology retellings, and I will usually pick a vampire romance over a book about whatever mythological pantheon.
What are your favourite and least favourite supernatural beings?
