For fans of Dan Simmons, Gene Wolfe, Neal Stephenson, A Canticle for Leibowitz and other classic metaphysical sci-fi...this near future technothriller dives deep into questions of consciousness, faith, and artificial intelligence.

When Artilects (next generation androids) begin reporting a strange apocalyptic vision that only they can see, most governments assume it is a hoax--or a hack.

Then one of them belonging to the wealthiest man in Africa shows up in the Basilica of Our Lady of Nigeria claiming to be possessed. The Vatican sends Fr. Gabriel Serafian, an exorcist and former neuroscientist, to investigate. Serafian quickly finds himself swept up in a conspiracy of global--and possibly supernatural--dimensions.
