Dive into the heart of Vatican intrigue with The Celestial Guardian, an adrenaline-pumping thriller that masterfully intertwines the shadowy corridors of religious power with the luminous frontiers of scientific discovery. This captivating narrative follows Father Michael Dominic, the esteemed Prefect of the Vatican’s Secret Archives, as he uncovers a remarkable artifact lost to time—Leonardo da Vinci’s most ingenious invention, the Celestial Guardian. Initially heralded as a divine instrument capable of forecasting a catastrophic asteroid bound for Earth, Father Dominic's discovery soon unravels a more ominous reality: the Guardian’s ability to not just predict, but alter celestial events.
As the revelation of its true potential threatens to shake the foundations of faith and science, the narrative propels readers into a high-stakes race against time. Father Dominic finds himself ensnared in a dangerous web of ambition and power, with factions including a power-hungry Vatican cardinal, vying for control of the Guardian’s world-altering abilities. Set against the backdrop of a Church grappling with transformative doctrines and the scrutiny of the world, Father Dominic must navigate his own inner turmoil while thwarting a global catastrophe.
