The New Ring of Solomon

Evil Jinn are invading our world, possessing and killing humans. The only ones aware and capable of stopping the incursion are a Sufi teacher, and his student. They must find the Shamir– a legendary device used to shape the stones of Solomon’s temple– and King Solomon's Ring.We learn the history of Solomon and his acquisition of these artefacts through Yusuf’s research. The Sufis will need to gather a band of unusually gifted seekers to perform the Sufi Ceremony of Remembrance (known as Zikr)to close the ever-widening rift between the human and jinn worlds.
They set out from from Berkeley to Los Angeles guided by tenuous dreams and signs, then Mt. Shasta, Yosemite and Crystal Cave. The band of seekers gathers new members while fighting off increasingly vicious attacks from demons and Jinn. Upon meeting NANCE in the Sierra foothills, they discover that she has inherited and named her husband’s yellow Cadillac bus The Shamir.
As the Jinn attacks become more brutal, Shaykh Daud explains that each one of the travelers constitutes a part of Solomon’s Ring. They are to perform the Ceremony of Remembrance (Zikr) in the Crystal Cave which will amplify the energy necessary to shut the dimensional gap permanently.
Yusuf continues his revelations about King Solomon and the legends of his use of magic. Pursued by demons driving one of Nance’s cars, a Plymouth Woodie, the bus is struck broadside and plunges down a hill and crashes, killing Shaykh Daud. Yusuf must now take charge before the army of Jinn engulfs them. They discover a hole blasted by the exploding bus revealing an entrance to a section of the cave.
They bury Daud quickly as the jinn and demons gather. Jumping into the cave they form a circle and begin the ritual. The crystals help amplify the energy but what at first seemed successful is quashed by the most powerful demon.
They attempt the ceremony again with their remaining energy and eventually succeed. The crack between the worlds is repaired, and each can return to their homes, enriched and strengthened for the next adventure.
