The book, released by the US publication 'Supreme Century' in English in April 2015, reached global book networks sooner than any other title on the same subject, Mehr News Agency reported.
Other books on Daesh that were published months after Porhelm's work include 'The Complete Infidel's Guide to ISIS' by Robert Spencer, 'The ISIS Apocalypse' by William McCants, 'Rise of ISIS' by Jay Sekulow, 'Inside ISIS' by Benjamin Hall, and 'ISIS Exposed' by Eric Stakelbeck.
The Persian translation of Porhelm's book titled 'ISIS and Jihad al-Nikah' was published in May 2015 and was warmly received by Iranian readers.
'War and Sexual Adventure in ISIS' depicts the atrocities committed by Daesh and the enslavement of women and the process of brainwashing and deceiving people into carrying out suicidal attacks for a chance to go to heaven.
