This book is really interesting for anyone that wants to know more about the concept of Evil and how it shaped the idea of the Devil (it is the first of a series of I think 3). There is a lot of knowledge, although there seems to be quite a bit of repetition, but that is not very bothersome (at least for me).

I don't think it is as accessible as many non-fiction books are nowadays, but I found it thought-provoking.
