The Book of Occult narrates the thrilling journey of Peter Ashton, who, following a dark past involving an occult ritual gone wrong, embarks on a quest to uncover the secrets of a mysterious book and its enigmatic author. This quest leads him into a perilous race against time and powerful adversaries, unlocking esoteric wisdom that has been hidden and disputed for thousands of years.

Peter's journey takes him from Paris to Los Angeles, where he encounters a Professor and an English Auctioneer who assist him in verifying the book's authenticity and origins. He discovers that the book is the last unpublished work of the 19th century French occultist, Eliphas Levi, a revelation that plunges him into a world of mystical conspiracy.

As Peter delves deeper, he finds himself the target of a former American government agent turned dark mystic, a cult leader offering him power, and extremists desperate for the book. A chance meeting with a beautiful gypsy woman offers hope and insight, leading him to a Spanish mansion with more revelations than he could have imagined.

Can Peter unlock the secret wisdom before it's too late? Or will he be seduced by the deadly forces that once tempted him?
