In Lumen, the third book in the Red Path Spirit Adventure series, the Illuminati increase their efforts to prevent another of the 40, 000 year old sacred sites from being activated by Cheeway and friends. As they journey to the sacred valley between the twin volcanoes near Mexico City, Cheeway's expedition encounters ancient underground passageways, an 11 foot green crystal pyramid, and the aid of spirits from the in-between world. Follow along with the group, as they confront physical and spiritual hurdles in their quest to keep the Illuminati from prematurely moving mankind from the time window of the Second Warning directly into the Third Warning of the End Times!
