More walls broken
(Book)

A trio of academics enter a deserted California cemetery late at night, bringing with them a number of arcane devices aimed at achieving an equally arcane purpose. What follows is the sort of dizzying, mind-expanding entertainment that only the always reliable, always astonishing Tim Powers could have written. These three men, professors in the "Consciousness Research" department at Cal State University, have come together to perform a seemingly impossible task. Their goal: to open a door between the world of the living and the world of the dead, and to capture the ghost of the recently deceased scientist Armand Vitrielli. For their own desperate reasons, they hope to avail themselves of the secrets Vitrielli left behind at the time of his death. Their experiment, naturally, fails to come off exactly as planned. A door between the worlds does, in fact, open, letting in something-someone-completely unexpected, and setting in motion a chain of events that will reverberate throughout the narrative. --from Amazon.
