The Spirit Phone

Aleister Crowley and Nikola Tesla confront the enigma of Thomas Edison's new invention: a phone to communicate with the dead.

It is August 1899, and Thomas Edison proclaims his most amazing invention yet: the Spirit Phone Model SP-1. At nearly the same time, a cocksure young mage named Aleister Crowley inexplicably teleports into the home of Edison's archrival, renowned inventor Nikola Tesla. 

As insanity and suicide multiply among spirit phone users, Crowley and Tesla combine their respective skills in "magick" and technology to investigate the device's actual origin and ultimate purpose. 

Embarking upon an adventure of astral travel, demonic invocations, and high-speed airship journeys, they are soon embroiled in a desperate race to stop the spirit phone's use by an unknown adversary to inaugurate a hell on earth from which none shall escape.
