Oliver Haddo has lived to experience the events and activities as described in Keep Calm and Hail Satan. Observing the lack of books that combine gastronomy, self-help and Satanism he commenced work on this project in mid-2014.
The author has travelled across the globe and spent extended periods in Egypt, Latin America and several European cities. During these travels he has often been shown great hospitality by a diverse spectrum of individuals who are viewed collectively as Satanists.
