The book I am reading at the moment. I'm only about twenty pages into it, and I can already dearly recommend it. Stephen T. Asma dives into the history of monsters, exploring various theories about various fears for known and unknown creatures and scenarios. Where do these fears come from? He refers a lot to my all time favourite; dear mr. Darwin.
No, it is not a fantasy book, it is psychology and humanity in its purest form. Read it!
(big thanks to the equipment borrowing technicians for being fifteen minutes late and using up my last bits of patience, for otherwise I wouldn't have stumbled upon these monsters)
