The Forty Rules of Love by Elif Shafak

I desire nothing. I fear nothing. I am free. 'Sufism' is the preliminary blueprint for the journey of promised discoveries. It is the seed that grew in his subsequent literary and poetic works. Therefore, this book can be considered a 'guide' leading the reader through Kazantzakis' fictional worlds, while at the same time, it can be seen as a key milestone for measuring his later development.
