In this 8th book of the Transylvanian Series, Peter Moon personally pursues the mysteries presented by the Romanian Sphinx in the wake of the adventures of Radu Cinamar and the scientific breakthroughs of David Anderson and his ability to control time itself. Bypassing the censorship surrounding both men, Moon directly contacts the Active Living Intelligence within the Inner Earth. This intelligence transmits information through synchronicity, visual downloads, and time events-all calculated to imbue the reader with the raw, unedited signal of human evolution. This signal reveals itself as an active, living Philosopher's Stone presenting the Magnum Opus not as a relic of the past, but as a threshold waiting to be crossed towards a state of immortality.
