A Dark Song (2017) is a cult movie that presents maybe the most realistic depiction ever of ceremonial magick.
Its heroine undertakes "the Abramelin ritual", an occult process for summoning her Guardian Angel, so that it might grant her stated wish to meet again with her murdered child.
Yet the ritual depicted in the film is not entirely fictional. It takes its name from an actual magical working, once attempted by the notorious Aleister Crowley, and undertaken by real-life occultists to the present day.
This book explores their experiences. It examines what the real-life Abramelin ritual is and the way it works. And it answers the question of how A Dark Song offers such a realistic representation of magick when angels and demons are not supposed to exist in reality at all.
